Thanks for all the replys i do believe it is mica i say a pic of some in a book that is identical to what i have thought it looked cool so i picked it up i will most likely put it on a shelf as a conversation piece lol

No, not a geologist, no piece of paper. I'm just a rock hound. I was trying to be glib and didn't phrase it well.
Phylite is slate trying hard to become schist. We are talking about the same kind of rock, just differing amounts of metamorphosis. Based on these photos, I'm not sure it's possible to call it either way.
I see lots of schist around here. We don't really try to differentiate the exact type. It's just more schist.

Baja,
I see, same here. But I'm a prospector without any papers, lol.
Jupp, we tend to say that if mica flakes/grains can be seen under loupe its closer to schist then phyllite.
Based on that we find quite a bit of phyllite up several miles northwards from my place.
I think we can settle the matter indeed.
