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.
