I was cutting a trench for a waterline, this thing came rolling out. Kinda grey from the clay when it came up. I thought I had an honest cannonball. Was pretty excited.

Do you guys think it might be a Geode, any way to tell without breaking it?

Could be a limestone concretion, aka chert nodule

Depends on the geology of your area.

Does it weigh less than a duck?

But, it does have a lot of extrnenal crystallization.

Get a masonry saw and slice it in half

Looks like cookies and rootbeer to me.

It's a geode.

Until you break it.

Got a rock store local, they will saw it in half for $20.

Pot luck on the guts.

I don’t know what it is but it wouldn’t stop me from making up a hell of a lie about it to impress chicks

Masonry saw huh?

LOL

summer interning, I had a guy walk into the geosciences dept, wanted to know if we thought what he had was a meteorite.

I went and grabbed our minerology PhD, we got him back outside, he was a little ‘fruity’

She asked if she could chip it little off with a rock hammer. He agreed.

She wailed on it once, pulverized it like chalk, look on his face was priceless. Scooped it up and said, nope, just a rock. Thanks for stopping by.

hahaha

Yup, if it’s a limestone concretion, it’ll zip right through. $4 blade

If it’s more up on the moh’s scale, then he moves up to to a $38 diamond tile blade.

Scientific method, start with a $4 hypothesis

You good with that?
Posted By: bigwhoop Re: Geode? - 04/01/20
It looks like the geodes we found in CO and broke a few open to reveal a hollow center with pink-purple crystals inside. Hollow areas of soil can form them but most are created as a result of volcanic activity.

Knowing that i dont know [bleep] about rocks... Wouldnt a meteorite be magnetic? Already had an oldtime at the shop hit it with a magnet.
Been riding in the back of the truck for a year. Just remembered it was in the bucket tonight while we were talking.
Posted By: slumlord Re: Geode? - 04/01/20
There’s a diamond mine, deposited in Arkansas, ancient activity. Could be geode

If that part of Missouri is near that part of ark

Possible more

Yeah, i'm pretty curious. The 38 wouldnt stop me. If I come up with a saw.

I'm in the Ozarks, on the Arkansas line. Probably just limestone, but I am curious.

If you want to have any chance at a nice specimen, whether it is a geode or not, pay somebody with the proper equipment to saw it correctly.
Posted By: ldholton Re: Geode? - 04/01/20
I've dug (excavation ) in SWMO for 30+ years .broke plenty of limestone. Never seen a limestone floater that round. And if we an isolated piece I'd bet heavy it is not just limestone

You ever find any petrified wood around there? Excavating?
Posted By: Fubarski Re: Geode? - 04/01/20
A decent percentage of the quartz crystals people pay to dig, just south of you, started off as a geode but were broken open through natural processes, or the mining of the crystals.

I'll try to find a place.

I'm close to your area. Like 45 minutes south i'm sure.
Never had a reason to ask, and its none of my business, but close for sure.

Never that had been noticed, but itsusuallyfast and furious, lots of arrow heads in certain areas

I've do a few projects in Branson , been as far south as Eurka Springs AR acouple times

I’ve got a chunk of petrified wood, about 16” long, 7” diameter.

Came out of northwest, middle tn—

Still has QAL quaternary alluvial fill packed in crevices, red clay. was excavated by a friend.

Trying to figure out exactly how got in more recent soil horizons. Unless it’s petrification occurred in thousands of years vs millions or unless some wild form of deposition and delivery happened to place it in 5 ft of clay.

It’s coniferous by appearance of grain striation

I have a petrified log.


It was a whole tree....sans branches of course.

Used to be able to go to Crater of Diamonds, Arkansas my grandmother was a rock hound. She’d go and scratch around in a plowed field with other enthusiasts.

It’s a state park now.

Not sure if they still allow digging or surface gathering.

Slice that SOB up, and take your family on a cruise:

Still open.

Worth goin, if you're in the area.

Especially after a rain.

Crystal mines in the area are much more fun though, especially with kids.

I know they did just a few years ago, I'm to lazy to search for a headline, but it seems like someone found a diamond worth some jack... probably been 5-6 years ago.
Posted By: slumlord Re: Geode? - 04/01/20
Might have to head over there some time. Ran across little clear pill bottle with the old woman’s crystals she picked up there.



We all used to go corundum ‘mining’ in Franklin North Carolina. Cowee Valley.

Buy buckets of dirt for a dollar and wash em in a screen, mill race of water. Find rubies, garnets, sapphire, rhodolite, etc.

The old woman loved that, I went back a couple years ago.

Epa or their local enviros cracked down on them for all the sediment delivery back into the streams. Only a couple remain open after engineering some holding ponds to abate the silt.

Google Weaubleau Eggs. Quite a few of them around this area.
Posted By: Valsdad Re: Geode? - 04/01/20
Egg is right.

I wouldn't open it for nothin'

Prolly gots one a them dino sores in it. Might still be alive even.

Don't want to unleash that kinda thing in these times now, do we?

Might even be ALIEN, and you could be releasin' somethin' worser than the Corona!

LJ, all kidding aside, I'd go with geode.

I hope it's a good one too.
