Need help identifying rocks

[sushidingo]

I found this stone in the woods and dont know what it is. It crumbles easily and there appears to be flecks of silver. Any help is appreciated

Decomposed quartzite with mica inclusions.

Rasputin is correct. I'll only add to that a bit with what your looking at are the individual crystals and mica that are fragmenting off of and out of the original host rock. Because your stone is what would be considered a mass, or massive, formation the individual crystals are all mashed up so there is not much hope for good individual crystals however you might get some gemmy bits.

Thank you for the information

Can anyone identify these please?

Not very clear scvrock, but my guess is Quarts with iron oxide and looks like mica or pyrite?

Looks like quartz with either arsenic pyrites or native silver just a guess
