An odd, hard thing with lots of pretty stuff. I collected a shelf specimen and some smaller handies for the archives (trying to collect examples of batholith margin pegmatic errrrratics.)

This is very uncommon in the watershed it came from but is not glacial moraine, I'm certain. There's also some metals which instead of rusty,  I believe it has autunite in it and that's radioactive decay halo as the low temp pegs carry uraniums.

 I imagine that if it has alunite in it that it must be a conglomerate that includes metamorphosed laterite soil.It looks like a metamorphosed igneous rock to me. Contact metamorphism on the edge of batholiths can do amazing things.

Lithic- the metal is Thorite!! I brought it to a guy here a we counted geigers.

I feel so ignorant of geology when you guys talk on some of these finds.  I've got great knowledge on types of agate and formations and locations but you are all on another level on the scientific processes.  Kudos

Kudos to you as well, Steve! Your knowledge base leaves me floored consistently. The fact that you know locations and forms so well is a super power.
