Help identify

[Seth Harville]

Found in London Kentucky in a creek. Not magnetic but maybe a little bit heavy. I appreciate the help!

looks like quartz with maybe mineral deposits from a cave formation?

Thanks NOLA Ken for your help! It’s a pretty interesting piece for me so I’m gonna keep it. I’ve seen a lot of quarts but none like this around it.

Yes, quartz with something else. Try
"The “top five” most abundant minerals are: calcite, quartz, pyrite, dolomite, and fluorite."
From
Minerals of Kentucky, Indiana, & Surrounding States.

Thanks GoldieLocks. I’m gonna go do some research on those and see if I can figure it out!

I think that is a concretion. A bunch of rocks stuck together with some kind of matrix. Gary

It may be ToddsPoint. If you look at the third picture, in the bottom right there is a brownish looking rock in it.
