Crazy Breccia. Can a likely cause be determined?

Would it be silly for me to suspect an impact related cause? Looks intensely and chaotically deformed. Photo #2 looks almost pseudotachylitic (maybe?), though it's kind of hard to make out as I just pulled this from a creek where it seems to have recently fallen off the sidewall.

Will post dry pics in comments asap.

Whose fault is this? Impact or tectonic?

Looks like it could be a weathered shatter cone. See the other photo in the comments section.

What kind of stones are geologically important right now?

For example I'm sure labs and museums would willingly accept meteorites and new fossil specimens, but what other sorts of things are important?

What kind of occurrences are sought after?

Can erratics be found anywhere?

Is the abundance and variety of erratics in the North unique? Or can erratics be found just about anywhere?

What are these wavy minerals?

Specimen (Photo in comments) contains strange clasts with wavy minerals inside; also some odd groupings of orbicular or botryoidal plagioclase (I think)

Never seen this before. Can someone educate me here? Thanks!

Hydrothermal alteration? Contact Metamorphism? Or even... Pseudotachylite?

Free slices on the house if anyone wants. DM me a shipping address.

How do I donate specimens to teachers or researchers?

I rockhound for unusual pieces as well as some mineral specimens with exemplary characteristics such as cleavage or terminated crystals that I can't always keep.

​

It pains me to have to discard them but I would be happy to ship them to researchers/educators at my own expense. Any help appreciated. Thanks!

Rock with metal on it.

Sort of has a tacky, rubbery feel to it; seems like it might be somewhat flexible. Barely magnetic on one of the corners. Pinpoint detector isn't picking anything up. Strange...

Is it possible for a chondrite to lack metallic inclusions?

In other words, could there be such a small amount of nickel-iron that a chondrite would be missed by a metal detector or fail to noticeably attract a magnet?

Igneous rock or Fossil?

Found in NY. Seems like an ordinary igneous sort of rock but up close looks like a coral colony. Could it be both?

Is this interesting?

I don't know much about rocks, but it looks like this rock has a story. Anyone know what it is and what might have happened?
