how hard would it be to mix crushed Chrysotile in with cocaine to destroy the trade?

Last question...I've got a big chunk of pegmatite on my desk. It has very distinct portions of quartz, mica and rosy granite. Where is the most likely place in the US that it came from?

Why is some argillite so unstable in drilling environments?



Good question! Maybe it's easy to wet the muds with fluids, destabilizing them? After all they are just dried out muds...

so a shale formation, is it actual rock?



Yes. Shale is a rock made of lithified silt and mud.



You can see really old shale in place in a lot of areas in the west around the foothills and hogbacks of the Rockies.


And of course, in core.

I'm holding a limestone rock in my hand from my driveway. How old is it?

I don't know, but the cheap answer is deep underground from a long time ago.

I'd say the Rockies or Appalachians

1) what color is it?
2) can you see any fossils?
3) can you see any crystals or is it chalky?
4) does it look broken or is it rounded?
5) does it make a thud or ping sound on a table top?


or

take a picture and let me see

Along the Front Range they are usually tilted, sometimes quite severely. As the granite that forms the Rockies was uplifted it pushed through the overlying sedimentary rock like a new tooth coming in. This caused the overlying rocks to fracture and tilt upwards in the direction of the mountains.



This of course is not shale but sandstone.

The real question: Where should I get a Masters in Geology.

Heavy background in structure and seismic processing/interp in undergrad/current employment.

I just called my 9 y. o. son in to give me some rock questions, and of course he can't come up with one. (He's a Pectus wannabe/rock hound who will immediately look down at any old pile of rocks to see what he can find. He can spend hours in the creek bed at our camp in Tunica Hills looking for agates and fossils.) he's always asking me questions I can't answer, and he probably knows more about rocks than me anyway since he reads about them all the time.

So here are my Q's:
What kinds of classes should I encourage him to take before college? Obviously science, but anything else?
Any good books for kids you can recommend?
What are the best places to take him around BR to look for rocks?
Do you know if LSU or anywhere else offers a geology camp for kids?

Thanks!

OK, checked my notes:

1.4 billion Pikes Peak Granite
1.7 billion Royal Gorge Gneiss

I felt like 1.7 was floating in my brain...just had to make sure.
