If I wanted to kill someone with a rock, which one gives me the best chance of doing it with one blow?

have you Joxied today? Either the gmt or lunch thread(s)?
Just saw it.
If you want an PetE job, try and find one. You can get those out the gate. You can also start as a mud logger and work up.
If you want a geology or geophysics job, get a masters in one of those.

I went on a cave tour in Arkansas and the tour guide said the cave was formed 10,000 years ago when I asked how old a structure was. So my question is. Was this tour guide an idiot?
Not necessarily. Caves are very ephemeral systems. They are made by groundwater and eventually moving water eroding and digging deeper and deeper into the dissolvable bedrock. A cave can be made in that time.
Do you remember what cave it was?

There is a clear, almost glass like rock found in the plains. Ive seen it in sheet form in northern Oklahoma. Many settlers used it for windows in their homes.
What is it called and how is it formed?
This?
That sounds like mica. It's actually a mineral! It's formed from the arrangement of silica molecules in a sheet like fashion. Due to this arrangement, this mineral is said to have perfect cleavage, and it's that cleavage that lets you peel it from itself piece by piece until you can get a layer that you can see through.
This form is muscovite. It's formed from cooling of magma at low temperatures over a long time.

Either big and blunt, or pointy.
Maybe obsidian?
Definitely not pumice.

It makes me happy I'm not that kind of geologist.
I do come out of the field the dirtiest and sweatiest and with the most filled pockets though.

My cousin once hit me in the head with a railroad rock. It left a scar.
Obviously dangerous, should there be a law banning them?
Serious question. When my grandfather plowed his fields in southeastern Ohio, he would unearth these black "glass like" rocks. I had one that was almost as big as a baseball. Always wondered what kind of rock it was. Very sharp edges.

If you pummeled someone with pumice would it be considered aggregated basalt?

Re: clear rock. I saw some once and was told that it was formed by lightning striking sand. I didn't really believe the person. Any truth to existence of rock formed in this way?

A lot of railroad rock is slag
dunno if it's a rock. Haha.
For the other rock: Do you know if the rock would leave a black residue on your hand? And was it light weight or rather dense?

I used to work next door to the Detroit Salt Mine Co. I have heard that their tunnels run all the way to New York. If they have been mining forever, what is the liklihood the earths surface will collapse?

Do you know anything about Spectrus granite? Or is that just a "lame name"?

Only if the pumice was mafic, but I don't think that can happen.

I think that's a way some guy gets money in Sweet Home Alabama.
It is called fulgurite.
All the fulgurite I've seen is dirty, because although it cooks the sediments where the lightning strikes, all the other surrounding sediments nearby melt slightly and adhere to the main body. So, the only way to get it clear is to sand and clean around it. Most fulgurite are really small and would make this hard, and not worth it because cool structures wouldn't be preserved. You might have this one spectacular one you could do it on...but why would you ruin it?

Rocks are great at bearing loads. Like really good.
Mines with tunnels that long are probably small tunnels, so it will stay for a long while.

Is it true that the Blarney Stone tastes like mono?

The lame names are the names that don't help you understand the rock, just the look.
The spectrus granite is a name that covers both. I had to look it up. Sometimes the problem is everyone considers any stone covering a counter top to be granite. This looks like it could be a pegmatitic granite or a gneiss. Either way, I like it! It's the kind I was describing as being the kind to get to another poster earlier.

How can I google facts about rocks?
