Does obsidian change into slate when under extreme pressure and heat?

Slate is primarily a sedimentary rock, originating from very fine clays deposited in deep water - or at least distant from shore. It is only mildly metamorphosed by heat and pressure. Often a good source of fossils.
Obsidian on the other hand is volcanic glass, generally derived from melting and re-freezing of rhyolite lava
