Copper Ore Minerals in Nature: What Arizona Has Taught Me

Living in Arizona long enough, you eventually pick up a thing or two about copper — whether you’re trying to or not.

It’s part of the state's identity. Copper is everywhere here. Arizona produces about 70% of the nation's copper, and you don’t have to look far to see the legacy. Giant open-pit mines scar the horizon, old mining towns dot the map, and off-roading adventures often lead you past rusting headframes, abandoned shafts, and relics of a boom long gone.

Drive through places like Bisbee, Jerome, or Morenci, and you’re not just seeing towns — you’re rolling through chapters of Arizona’s mining history, places where communities grew up around copper and where geology shaped destinies.

And if you spend enough time out here — in the desert, around rock shops, or listening to old timers at a diner — you’ll eventually learn the difference between malachite, azurite, and chrysocolla, without even realizing it.

Arizona’s World-Class Copper Deposits

Arizona sits on some of the largest porphyry copper deposits (these happen when there's hydrothermal fluids coming from a magma chamber) on the planet. These aren’t just little copper veins; they’re huge, low-grade ore bodies mined at an industrial scale.

 Major Copper Mining Areas:

- Morenci Mine - Currently the largest copper mine in North America.
- Bisbee - A historic mining town famous for producing vibrant azurite and malachite specimens (and turquoise too).
- Globe-Miami, Ray, and Bagdad - Other significant mining towns with long histories and still-active operations.

These deposits formed during a period of intense volcanic and magmatic activity called the Laramide orogeny (about 70–50 million years ago). Later, surface weathering oxidized the upper portions of the ore, creating colorful, collectible, and economically valuable oxidation zones.

The Three Layers of a Copper Deposit

When copper ore is exposed to air and water over geologic time, it weathers and oxidizes. This creates three distinct vertical zones in a typical copper deposit:

1. Oxidation (Supergene) Zone
- Near the surface.
- This is where oxygen, water, and CO₂ react with primary copper sulfides.
- You get beautiful green and blue minerals like:
  • - Malachite (Cu₂(CO₃)(OH)₂)
  • - Azurite (Cu₃(CO₃)₂(OH)₂)
  • - Chrysocolla (hydrated copper silicate)
  • - Cuprite, and even native copper
These minerals are softer and more vibrant than the original ore.


2. Enrichment (Secondary Sulfide) Zone
- Below the oxidation zone.
- Copper-rich water seeps downward and re-precipitates copper sulfides in higher concentrations.
- Minerals like chalcocite and covellite form here.
- This zone can be economically valuable because copper grades are enriched.

3. Primary (Hypogene) Zone
- Deepest layer - untouched by surface weathering.
- Contains original copper sulfides like:
  •   - Chalcopyrite
  •   - Bornite
  •   - Pyrite
- This is the true "source" ore before any surface processes altered it.

Common Copper Oxide Minerals You’ll See in Arizona


Malachite
- Deep green, often banded or botryoidal (rounded).
- Forms in the oxidation zone as copper reacts with carbonate and water.
- Soft and easily scratched, but striking in appearance.

Azurite
- Deep blue and more crystalline than malachite.
- Often alters into malachite over time with exposure to water.
- Rare and beautiful - highly collectible.

Chrysocolla
- Bluish-green, often glassy or earthy.
- Forms when copper reacts with silica rather than carbonate.
- Less structured, softer, and can resemble turquoise.
- Common in Arizona’s weathered copper zones.

What’s Happening Chemically?

These minerals form because of simple but powerful chemistry between copper, air, water, CO₂, and sometimes silica.

 Step-by-Step:

1. Oxidation of Sulfide Ores 
   Copper sulfides (like chalcopyrite) break down when exposed to air and rainwater.  
   This reaction releases sulfuric acid and copper ions (Cu²⁺) into groundwater.
2. Carbonate Minerals Form 
   When CO₂ from the atmosphere dissolves into water, it forms carbonic acid, which then reacts with copper:
   - Forms malachite and azurite.
3. Silicate Minerals Like Chrysocolla  
   If silica is present (from weathered volcanic or granitic rocks), copper bonds with it to form chrysocolla, a hydrated gel that later hardens.

The Environment Plays a Huge Role


Several factors control what minerals form and where:

- pH: Slightly acidic conditions help break down primary sulfides.
- CO₂ availability: Needed to form carbonate minerals.
- Water movement: Transports dissolved ions.
- Silica presence: Essential for chrysocolla.
- Time: These reactions play out over thousands to millions of years.


Final Thoughts

Whether you’re studying geology, hoarding rocks like a caffeinated prospector the way I do, or just out in your 4x4 trying not to get stuck in a wash, Arizona’s copper story is everywhere. It’s scrawled across road cuts, whispered through ghost towns, and practically winks at you from every piece of jewelry at a roadside stand.

So next time you're bouncing down a dusty trail and spot a bright green or deep blue rock, don’t just kick it aside — that could be a chunk of malachite with a better backstory than your Jeep (prove me wrong). Around here, even the rocks have history, and some of them probably have ghost town gossip to spill.

How to Start A Rock Collection

----------------------------------------------------------------------------------------------------------

So, how do you start a rock collection?

a beautiful rock collection organized in tiny white boxes for display at a gem show

Well… if you’re even asking that question, chances are you already have one!

Think about it—do you have a couple of cool rocks sitting on a shelf, in a drawer, or tucked away in your garden? Then congratulations, you’re officially a rock collector.

Even if you haven’t started yet, it’s easy! Just head outside. You don’t need to hike for miles or drive far away —amazing rocks can be found right in your backyard, at the beach, on a trail, or even in a parking lot.

Look for anything that grabs your attention:

  • A unique shape (I always stop for a rock with a hole in it!)
  • An unusual texture or color
  • A pattern that looks like something magical
  • Or just one that feels special for no real reason

Some of my favorite rocks aren't fancy or rare—they’re just reminders of a place, a moment, or a memory.

You don’t need any special tools to get started—but if you catch the rockhounding bug (it happens!), you might want to invest in a few basics. I put together a list of 10 essential rockhounding tools here to help you level up.

A few friendly rockhounding tips:

  • Be respectful of the land. Don’t take rocks from private property without permission.
  • Try not to over-collect—leave some treasures for others (and the environment!).


Once your collection starts growing, you’ll probably want to know what you’re actually picking up. Don’t worry if you don’t figure it out right away—even experienced collectors have mystery rocks!

Learning to identify rocks takes time, and even experts get stumped. Many minerals look similar, and the same mineral can appear in a variety of colors or forms.

This book, which is also on my top 10 list, has helped me out a lot—it's a great reference for identifying common rocks and minerals.


Want to go beyond local finds?


Visit rock, gem, and mineral shows near you. Vendors often sell stunning specimens from all over the world - perfect for expanding your collection and meeting other enthusiasts.  

Or if you prefer to shop online, there are plenty of options, but it's important to know what you're getting. Here are a few tips to help ensure your minerals are the real deal:

  • Natural Variation: Genuine minerals often have natural color shifts, imperfections, or are still attached to pieces of host rock (matrix). Inclusions (small internal features), are also a good sign of authenticity.

  • Price Point: If a deal looks too good to be true, it probably is. Pricier stones like moldavite or diamonds are frequently faked. On the other hand, more affordable stones like fluorite or agate are less likely to be counterfeit—but be aware that agate is commonly dyed (gorgeous, yes, but not natural).

Check out Desert Snail Minerals for a curated selection of rocks and minerals.  Many of their U.S. specimens are hand-collected, giving a personal connection to each piece.

If you love both display specimens and wearable pieces, Grumbly Tumbleweed offers a fun mix of unique finds.  From necklaces and bracelets to gifts like this rockhound coffee mug - perfect for kicking off your day - or a cozy cup of tea to celebrate your fresh organized rock collection, there's something for every mineral enthusiast.

Getting into rock collecting is surprisingly easy - just bring your curiosity and a love for dirt! But let’s be real: while you can start with nothing but your hands and a good attitude, having the right tools can mean the difference between a frustrating day (bandaging your wounds with duct tape in the back of your Jeep) and finding a bunch of sparkly treasures.

I’ve been poking around in rocks since I could walk, and I’m still finding new gadgets that make the hunt even more fun (and a lot less painful). Whether you’re a pro collector or just figuring out the difference between limestone and granite, here are 10 tools I actually use—and why you might want to pack them too.


 1. Rock Hammer - If you only bring one tool on your first rock-hunting adventure, make it this one. A rock hammer is basically your best friend in rockhounding - your trusty sidekick for smashing, chipping, and revealing the treasures hidden inside stones.

If you want something that’ll last longer than your current Pinterest obsession, Estwing is the gold standard. Their 13 oz Rock Pick with a smooth face and shock reduction grip is practically indestructible - and your wrists will thank you after a long day in the field. 



2.  Chisel - When brute force just won’t cut it, a good chisel just might. These are perfect for prying out delicate specimens without turning them into gravel. It’s a smart move to carry a set of cold chisels in a few different sizes, so you’re ready for whatever the rock face throws at you - whether you're working with stubborn veins or crumbly layers.

If you want a reliable starter set, the Stanley 4-18-298 Cold Chisel Set (3 pieces, yellow/black) is a solid pick - durable, dependable, and easy to spot if you drop one in the dirt.

Also, I have a secret weapon: a cheap old screwdriver. Seriously - those 50-cent yard sale screwdrivers? Perfect for poking around in dirt, loosening tight crevices, or doing the kind of prying that would make a chisel cringe. They’ll get beat up, but that’s their job.



3.  Paintbrush - You might be thinking, “A paintbrush? For rocks?” Yep. And once you try it, you’ll wonder how you ever lived without one. When you're brushing dirt and debris away from delicate crystals or fossils, the last thing you want is to go in swinging with something too aggressive.

I swear by Wooster brand brushes - they’re my go-to for everything from painting houses to gently uncovering hidden mineral gems. The Wooster Brush Q3108-1 Softip is the perfect size for getting into the tight cracks and crevices of outcrops without disturbing the goodies inside. It's soft enough to handle fragile specimens, tough enough to survive the trips in a dusty backpack, and best of all - super budget-friendly.

Seriously, don’t overlook the humble paintbrush. It’s like the toothbrush of rock collecting… only less weird to carry around in public.




4.  Safety Glasses - When chunks of rock start flying, rockhounding gets real... and dangerous. One rogue shard is all it takes to turn a great trip into an emergency room story. So do yourself (and your eyeballs) a favor: wear safety glasses that can take a hit without fogging up or sliding off your face.

And no, you don’t have to rock the “mad scientist” look with oversized chemistry-lab goggles. There are actually some great options that look cool and keep your vision intact—like these polarized safety sunglasses by Carhartt. They protect your eyes and your street cred.


5. Gloves – Your hands will thank you later. A good pair of gloves can save you from sharp rock edges, thorns, surprise tool slips, and the kind of scrapes that make you rethink your life choices. Durable, cut-resistant options—like leather or reinforced synthetics—are usually the way to go. Just make sure you can actually move your fingers.

Now, full disclosure: I hate wearing gloves. Always have. I can’t stand how they dull your sense of touch, how the fingers are always weirdly long, and how that awkward floppy space at the tip turns me into a clumsier version of myself (how is that even possible?).  Picking up anything smaller than a grapefruit? Forget about it.

But—miracle of miracles—I actually found a pair at Menards that fit well enough for me to wear without rage. They're snug, they don’t make my hands feel like I’m wearing oven mitts, and they’ve saved my fingers more times than I can count while digging through rough terrain.

If gloves drive you nuts too, give these a try. Your hands (and your patience) might finally be able to get along.


6.  Loupe - Don’t let its size fool you. A loupe is basically a pocket-sized magnifying glass that helps you get up close and personal with crystals, minerals, and those tiny details that your eyeballs alone just can’t catch.

It’s the kind of tool that disappears into the corner of your rock bag until the exact moment you need it - and then you’re so glad it’s there. I’ve been using a 40x Illuminated Jeweler LED UV Lens Loupe I picked up a couple of years ago, and it’s still going strong. Bonus points for the built-in lights - it’s like having a flashlight and a microscope in one.

Stick one in your bag. Your inner nerd will thank you.


7.  Mineral Identification Book - So, you’ve found something shiny, weird, or downright beautiful… now what? While apps are handy in a pinch, nothing beats flipping through a real book when you're out in the wild - especially when your phone battery is barely holding on for dear life or there's no signal in sight.

I’ve got a whole bookshelf full of rock books, but my go-to - the one that always ends up in my bag or at least in the Jeep somewhere - is the Smithsonian Nature Guide: Rocks and Minerals: The World in Your Hands (DK Nature Guides). It’s detailed, easy to use, and packed with photos that actually look like real rocks I could find.  

Trust me, there’s nothing more satisfying than ID’ing your latest find before you’ve even left the site.




8.  Backpack or Rock Bag - Rocks are heavy. So.... While stuffing your pockets with rocks seems convenient at the time, it's not ideal - unless you like walking with one side of your hoodie banging into you with every step you take or constantly tugging at your cargo pants.

heavy-duty backpack or canvas rock bag with reinforced stitching is a must. Some even come with compartments for tools, snacks, or your growing collection of “maybe cool, maybe not” finds. Personally, I bring two bags:

  • One rugged canvas shoulder bag (like this one from Rothco) for tools

  • And a lightweight foldable bag I stuff inside it, just in case I come across something too cool to leave behind.


9. Storage Containers & Wrapping Material - Once you’ve unearthed your prize specimens, you’ll want to get them home in one piece. That’s where storage and wrapping come in.

Small plastic containers (you can line them with foam if you’re feeling fancy), egg cartonsnewspaper, or bubble wrap all work great. But honestly? Good ol' toilet paper is one of the best materials out there. It's soft, surprisingly durable, and let’s face it—there's always a roll nearby. Just grab one from the bathroom or toss an extra roll in your gear bag or vehicle.

Because nothing’s worse than getting home, opening your bag, and realizing your perfect little crystal is now six disappointing pieces.

  

10. UV Light - Think rockhounding ends when the sun goes down? Think again. A UV flashlight is like having a secret decoder to help identify minerals - some of the coolest specimens glow under ultraviolet light, revealing colors and patterns you’d never see in bright daylight.

The ALONEFIRE SV003 10W 365nm UV Flashlight is one of my favorites. It's compact, rechargeable, and powerful enough to light up fluorescent minerals brightly. Just shine it on your finds and watch the magic happen—calcite, fluorite, willemite, and more will light up like neon signs.

Plus, using a UV flashlight in the dark makes you feel at least 10% cooler.  Science.





Rockhounding isn’t just a hobby—it’s a hunt, a science, and an adventure all rolled into one.

Whether you're just dipping your toes into the world of rockhounding or you've already got a garage full of mystery minerals and questionable "maybe keepers," having the right tools can make all the difference. From your trusty rock hammer to the humble roll of toilet paper, every item on this list earns its spot in the bag.

The best part? You don’t need to spend a fortune or have a geology degree to start—just a good pair of boots and a curious mind. Get outside, start exploring, and don’t be afraid to get a little dirty. Who knows what treasures are waiting for you?

Happy rock hunting—and may your rock bag be full and your pockets not too ripped.

Geology of Everyday Things: Drywall

 Diving into the Geology behind the Material:  Drywall

Drywall Cut Open for Repair

Spoiler alert:  If you're part of the 95% of people in the United States who have drywall in their living space, you have rocks in your walls!

Moldy Drywall needing Repair

Let’s talk about drywall, not just as a material we buy at the local Home Depot to swear at while we patch and paint, but as a product that blends geology, chemistry, and human ingenuity together.

Any homeowner or contractor will tell you, there’s a moment, usually after busting down an old sheet of drywall or carefully cutting into a wall for a repair, when they've paused to think: "What the heck is this stuff?"

That’s where I found myself this week, face-deep in dust, tearing up another wall.  This time it one was in a 1960s house that had termite damage.

The drywall was brittle, held up by a patchwork of rusty nails and slightly less rusty hope.

As I started beating it with a hammer and pulling out sections with my hands, something about the powdery crumble and debris cloud made me pause. This isn’t just building material. It’s made of rock!

What Drywall Is Really Made Of

Older homes can be a patchwork of building eras. Some walls are lath and plaster, others are early drywall, and a few are sticks and leaves... maybe?  

When you cut into them, you’re cutting into history — layers of paint, creepy wallpaper, and untold stories. But no matter the age, most of what we call “drywall” is gypsum board: a sandwich of gypsum plaster between two sheets of paper.

At the heart of drywall is gypsum — a naturally occurring mineral called calcium sulfate dihydrate (CaSO₄·2H₂O). It forms in sedimentary environments, places where ancient seas or lakes slowly evaporated, leaving behind concentrated layers of minerals. Over time, these layers hardened into rock.

That soft powdery layer in your wall? It's from evaporite deposits, possibly formed millions of years ago in a prehistoric sea. 

Kinda wild.

From Earth to Wall

Here’s the short journey from geology to your living room:

Drywall Patch on Wall

1. Gypsum is mined from surface quarries or underground deposits.

2. It’s crushed and heated to drive off water, turning it into plaster of Paris.

3. Water is re-added, it’s poured between paper sheets, and then dried and cut into panels.

4. You (or someone like me) screw it to your studs, tape the seams, and coat it with joint compound.

Simple? Sure. But behind that process is a deep connection to the Earth’s history — to evaporated seas, shifting continents, and chemical transformations.


Or... It Might Not Even Be Natural

Modern drywall doesn’t always come from mines. A lot of it — especially in North America — is made from synthetic gypsum, a byproduct of coal-fired power plants. When sulfur dioxide (a pollutant) is scrubbed from smokestacks using limestone, it reacts to form gypsum. That gypsum is chemically identical to the natural stuff and gets reused in drywall, keeping it out of landfills and cleaning up the air at the same time.

So next time you hang a panel, you might be putting up recycled pollution — and that’s a good thing.


Thinking Beyond the Walls

Working on an old house can feel like archaeology. But even in new builds, when you're working with drywall, you're handling a material shaped by deep time and modern innovation. That panel you just cut?

- It might be 300 million years old, from an ancient seabed.

- Or it might be less than a year old, born in a smokestack scrubber.

- Either way, it’s rock turned architecture — a literal wall between the past and your present.

So yeah, next time you’re hanging drywall, sanding a joint, or cursing that last screw that you just dropped on the floor… just remember: you're working with the Earth itself. Not bad for something we usually just paint over.

Blanchard Springs Caverns - A Must-See Destination on Any Arkansas Adventure

This blog entry is a little different, since you can't take the rocks here home.  In fact you can't even touch them because they're very fragile, but they're insanely beautiful.  



Last week, I unexpectedly found myself in Mountain View, Arkansas.  Don't get me wrong, I wasn't like, led there blindfolded or anything weird like that.  I had just driven across the country from Phoenix, Arizona to meet some family members from Wisconsin in Missouri.  Then suddenly, here we were... in Arkansas.

Our personal lives and reasons aside, we were looking for something interesting to do near Mountain View.  After getting what was quite possibly the best latte I've had so far this year at Moonshot Coffee in town and scanning Google maps on our phones for interesting local destinations, we headed to Blanchard Springs Caverns.  I am so glad we did!  


Blanchard Springs Caverns is an awesome spot for anyone ready to dive into the underground world. This place is famous for its gorgeous rock formations and stunning natural beauty, making it a must-see for nature lovers, thrill-seekers, and geology fans alike.

Many other caves in the United States have a special place in my heart, both the touristy kind you can bring grandma and the baby to as well as the kind where you're belly crawling with your helmet scraping the ceiling and a flashlight in your mouth... 

However, this cave deserves the State Fair blue ribbon when taking all aspects of the underground world into consideration.  The rooms are enormous, the formations are breathtaking, the lighting was meticulously placed and is thoughtfully controlled in both color and intensity.  

It was about a 25 minute drive through the Ozark Mountains of northern Arkansas past a really cool looking Tipi Campground / Retreat that we didn't have time to stay at (maybe next time!).  

At the caverns, there's a huge parking lot for cars, trucks, RVs, or trailers.  We even saw a big green tractor there.  

We purchased our tour tickets in the building, but they recommend purchasing them ahead of time at https://www.recreation.gov so your spot is guaranteed.  Yes, they do have restrooms and a gift shop on site. 

With about an hour and a half before our tour started, we went to explore the area.  Don't miss the chance to check out Blanchard Springs, the ruins of an old mill, and some pretty cool fishing spots nearby.  





A Quick History Lesson

Our tour guide, who was super informative, told us that Blanchard Springs Caverns was "discovered" in 1960s, but she said there was evidence that people had explored it long before.  It became property of the National Forest Service, who decided it was beautiful, and that the public should be able to see it.  Due to the amount of construction that had to be done very carefully to not damage the fragile cave formations, lack of funding, and delays from the Vietnam War, the caverns weren't opened to the public until 1973.  

A Quick Geology Lesson

While there are many types of caves in many different types of rocks, Blanchard Springs Caverns was formed in limestone rock, which is a sedimentary rock made up mostly of calcium carbonate (CaCO₃).  

Limestone bedrock is vulnerable to a process known as chemical weathering, which leads to the formation of caves.  Water is the driving force behind the creation of limestone caves. The primary process is carbonic acid dissolution. Here’s how it works:

  1. Rainwater absorbs CO₂ forming a weak carbonic acid.

  2. Rainwater seeps into the ground, absorbing more CO₂ from the soil and becoming more acidic.

  3. Acid reacts with limestone to dissolve the rock and create unique calcite formations, such as stalactites and stalagmites.

  4. Cave Expansion: Over thousands to millions of years, this dissolution process continues, gradually enlarging the cracks in the limestone. Eventually, these cracks widen and connect to form a cave system. The process is very slow but leads to the development of extensive underground chambers and passageways.

Blanchard Springs Caverns is a living cave, which means that the stalactites, stalagmites, cave drapery, cave popcorn, soda straws, and all the other types of beautiful underground rock formations are still growing.  As long as water is flowing through the limestone and depositing calcite, the formations remain active.   


Tours and Fun Stuff

Blanchard Springs Caverns has three different tours, each offering a unique experience:

1. The Dripstone Trail (Easy, Family-Friendly Tour)

This is the tour we took.  Our tickets were $16.00.  It is the most popular tour and perfect for people of all ages. The Dripstone Trail is a half-mile walk through the cave, showcasing gorgeous formations like delicate drapes, shiny flowstones, and tall stalagmites. It’s an easy stroll with paved paths and handrails, so even if you have some mobility issues, you can still enjoy this incredible underground world.

2. The Discovery Tour (Moderate Tour for the Adventurous)

 If you want to explore more of the cavern, the Discovery Tour is a great pick. This one takes you deeper into the cave, showing off areas you can't get to on the Dripstone Trail. You’ll see some cool geological features, including the cave stream.  It's about 1.2 miles with about 700 stairs.  This tour is only available Memorial Day through Labor Day.  

3. The Wild Cave Tour (For the True Adventure Seeker)

 If you’re up for a real adventure and in good shape, look into the Wild Cave Tour! You’ll crawl, climb, and squeeze through tight spots. You’ll see parts of the caves that most folks never get to check out. Contact the caverns directly to inquire about this tour at (870) 757-2211.


Tips for Visiting

- **Plan Ahead:** The caverns get busy, especially in peak seasons, so look up tour times and book your tickets ahead if you can.

- **Dress Right:** The caves are pretty cool year-round (about 58°F/14°C), so bring a light jacket or sweater, and wear good shoes, particularly for the Discovery or Wild Cave tours.

- **Be Ready for Some Stairs:** While the Dripstone Trail is pretty accessible, the other tours involve more physical activity like climbing stairs and navigating bumpy paths, so make sure you’re up for it!

- **Bring a Camera or your Cell Phone:** Our tour guide turned up the lights a few times so we could take better pictures and gave us tips on cave photography!


Short Version

Blanchard Springs Caverns isn’t just a cave – it’s a glimpse into the Earth’s history, where beauty, science, and adventure come together. Whether you're a casual visitor or a serious caver, there’s something for everyone here. So, if you’re ever in Arkansas, make sure to take a trip into the Ozarks and check out the amazing wonders of Blanchard Springs Caverns. You’ll totally love it!
