Identify This Rock!

[Oafman]

I'm really more sad about the prospect of breaking my rock....

I admit that this rock has been around since long before there were any humans interested in breaking it, but console yourself with the fact that you're doing this for science. Kind of.

What if I find a similar rock, and break it apart? Also, I don't have a geology hammer. Just a normal one. And a bigger normal one.

You don't need a rock hammer. You will likely mar a regular hammer a bit, but that does not mean that you can't use them.

I'll post pics when I get back up there, find a similar rock, and crack it apart.

Cool, and if possible as accurate of a location on a topographic map would help. I assume that this is not in your own backyard so you would not be giving out personal information.

I'll see what I can do.

According to a friend, the rock is actually a fossilized piece of a quilt.

This is a significant discovery!

Rock
​

Can somebody explain why this rock looks this way? Frankly, I find it suspicious. And to keep this relevant to the C&E section, I'd like the young earthers to take a go at this as well.

A guess based on the two images:
A weakly metamorphosed rock with two perpendicular joints and were filled by hydrothermal deposit.

If you just want an one word name, then "quartzite" is not a bad one.

 

[juvenissun]

They are quartz veins but other than that I have no idea about it. I don't know how that stuff forms either.

It was probably either a sandstone or an igneous rock (can not see clearly on the images. I bet it was a sandstone). It was compressed tectonically and the criss cross fractures were made. Then hot watery solution invaded into the fracture and solidified.

Not too complicated.

 

[juvenissun]

Is there any chance of finding the bigger piece of rock that this came off of?

It should be everywhere nearby the area found.

 

[juvenissun]

Southern Arkansas. On a mountain. No water or river flows nearby.

It sounds right. The Ouachita Mt. is loaded with this kind of rocks.

 

[juvenissun]

Our first young earth explanation!

In fact, according to the current geological model, this rock could be made from loose sand in a few millions of years. It does not have to be old.

Hey juvenissun, did you attend a few geology lectures lately?

The rock shown in the image does not worth $5.

In what capacity?

How dare you.....

 

[juvenissun]

How dare you.....

Well, then I take it back.
IF you are a good artist, then you may make it worth, say, $500.
But, I warn you, this rock is super hard. So, wear your goggles when chip it.

The photo in the OP looks to me to be some kind of sandstone. However I could very easily duplicate that and it wouldn't be hard to do.

I also notice it's very clean, did you wash it?

No, but thank you.
