jesus christ pot

they're minerals

one on the left is the parent rock, B is the metamorphic rock

B looks like talc, but I'm not an expert. It is metamorphic and white.

geology protip the answer is almost always quartz or granite.

wait whats a parent rock? can rocks have babies?

I'd guess he meant igneous. Parent does indeed sound dumb, but that's just jargon for you.

vhalin is geologist i think pls contact

left one is grainy could be a sedimentary rocks need full picture :/
it could be anything at the moment do u know where did you find them?

isn't B marble? Talc is a mineral, not rock, you should be able to know testing the hardness.

Thinking more about it... it could be sandstone > quartzite

I don't think they're his, considering it's a screenshot of the photo (dat whitespace). It's a test thing he has to take.

pumice is bouyant

OBJECTION
Rocks are made of minarals

It's hard to tell since colour varies so much, but talc is a mineral so I'll change it to sandstone and quartzite.

a is granular calcium carbonate which metamorphoses into b, marble

Wait there are types of rocks?
