#rock id

Who wants to help me ID some rocks?

So one of the cool things that got left at the new house is the former owner's rock and fossil collection, which they meticulously catalogued by which I mean they left them out under some junipers in the back yard. The power is out, so I'm spraying some of the dirt and leaves off with the hose, but if anyone has guesses I'd love to hear them.

1. The Big Fucker:

(10 in screwdriver for scale)

First clue that there was a secret collection, this was the only one really visible. Pale translucent blue-green cubic crystals and skinny, more opaque/white ones on top of a heavy dull white rock. Pretty, whatever she is.

2. Salt n Peppa

Pretty sure the black stuff is smoky quartz, but what are the white cubes and the red rock it's on?

3. Sparkly Bois:

Two of these- I think the little cubes are pyrite, but what's the dark, shiny/metallic stuff? Very heavy for their size.

4. Assorted Dead Things!

Fossil clams and a coral I think, but if anyone knows anything more specific I'd love to hear it. Pretty sure most of these things are from the Rockies/front range area but genuinely, I don't know where they got them.

5. IDK what she is, but her name is Helen:

Like a bunch of criss-crossing wafers. Not very heavy for her size.

6. Green Stuff:

What are the green crystals coming out of this rock? They're cool, whatever they are.

7. Miscellaneous Shinies:

Assorted small rocks I found while digging. Small dead clam, I think some of that is mica, and I'm really curious about the shiny stuff on the granite (?).

Part 1/2, gonna hose some more rocks while y'all speculate.

I’m far enough into my geology degree for my friends to ask me “what rock is this” every other week……

what have i done

[itsdappleagain]

science side of tumblr!!!

anyone know what this rock is?? i can't figure out from research what it might be/what formed it this way.

will send more pictures/answer more questions if needed 👍👍

even if you don't know i'd be really appreciative if you reblogged so i cna try to get this solved :D

Found in pile of misc rocks meant for landscaping

I’ve never seen a rock like this usually I’m good at identifying but this one is very unique but I have a hunch it might be petrified wood or something igneous based It feels very smooth and shiny near exactly like a lava flow rock but it’s wrong color

And there’s ragged blocky structures

it might be a matrix of several minerals but it feels igneousy

See what I mean it looks lava flowly but the colors are light

Conclusion: it's most likely angelite.

Can someone help me identify this rock? I got it at a market and it didn't have a label.

I tried google but I'm just not knowledgeable enough.

Reblogging so more people see is appreciated!

Idk if it will help but it almost feels powdery? Really soft, like I always think there must be residue left on my hands but there isn't.

It's harder than my fingernail but softer than a nail I had lying around. It can be scratched with a knife!

BTW, can anyone tell what is up with this rock?

It looks like a fossil, and my gut says "fossil skin," but I don't actually know. (The vendor I bought this from said he had no idea either, but was leaning towards "trilobite"?????)

I'm scared of asking Reddit so I ask you-- is this a moss agate? I can provide more photos of this if anyone needs (:

[marmorkreb]

it's the magic gravel because i keep finding inexplicably insane specimens to the point where im staring at the ground more than im doing actual work it kind of seems like what i imagine how a gambling addiction feels

giant chunks of druzy quartz and green tourmaline (I think?) and pyrite pseudomorph and phantom point??????

apparently we've been using this same pile of gravel for like 2 years but we've been pulling from it again recently bc the last hurricane washed out like half of the farm roads so everywhere's full of cool fresh rocks

Need help to id these rocks

[0luna123]

Found this cool-ass rock on a beach today.

Can someone explain what is this red circular part? Is it a fossil?

[lynx-the-beast]

Check out this cool rock my cousin found. Anyone know what kind of rock this is?

[suntvilling]

Help Geology Tumblr!

My aunt found this rock and we have no idea what it is.

It’s pretty smooth in parts and has holes in parts. It’s beautiful and very unique. Does anyone know what this is?

hear me out the other day i woke up and was immediately hit in the face with "7 year gap narumitsu in europe where phoenix kisses edgeworth in a low moment and then tries to flee and edgeworth uses mind chess on him to get the truth out of him which is a completely normal and ordinary average way to discuss your relationship"

[elitefourlacey]

Anybody know what the rock is? I've never seen that image before.

listen to me. if youre an adult you have the ability to be an unfathomably kind influence on a child. i had a good teacher who let me break down in the hallway for the whole period because he noticed me crying in class, and before that he complimented my writing skills and encouraged me to persue writing. and man ill never forget that teacher as long as i live for even the miniscule acts of kindness. be kind to kids. you never know whats going on that you cant see.

Can anyone help me id this? found during field work in the top part of the rhyolite lava flow, doesn't react with hcl, is almost too soft to scratch glass, found as thin coating on few rocks, there was a lot of chrisocolla and some other copper minerals in that outcrop, there was also some hydrothermal activity in that area (porous part of lava flow had some post gas voids filled by barite, quartz etc.) i would appreciate any answers, especially if you could also provide some arguments for your pick
