Is This Shale


Recommended Posts

Posted (edited)

Hi everyone,I'm new to fossil collecting and I live in Chester Illinois. I live by these bluffs and picked up a bunch of chunks of this stuff which I'm not sure what it is,Could it be Shale. These bluffs are besides the Mississippi river. Before I started working on them, I just wanted to make sure it is something that may hide some fossils of which I know shale might. Thanks for any help anyone could guide me.

This does seem to be very fragile and easily breaks and flakes

To me it looks like a laminated siltish two clayish sedimentary rock. If the stones split along planes of Weakness into thin sheets, it is shale, if not, it's a mudstone.

Ye have found some pretty neat fossils in shale eg this shrimp

It is certainly a thinly-foliated sedimentary rock; shale being the most likely of several related types.

It's splits along the layers and is very fragile. I just dint know if I'll be wasting my time with this stuff, but I thought it was Shale, but I'm a novice, so I dint know

it looks like a calcareous shale. there are shales with lots of fossils in them, and lots more without fossils. The New Albany shale is a good example in IN,KY,OH, 200-300' feet of almost empty shale. If you find any fossils in your shale there will probably be more. Good hunting!
