does anyone know a good website for rock Identification, with pictures and all. i've collected a lot of rocks from a long emptied stream near my house, there are a few different types..
one type is a slightest reddish sandstone looking rock.
slate of course.
some sort of granite that seems to have a lot of different stuff mixed into it.
looks kinda like... this
for to make sure it's aquarium safe?
