After obsidian has been erupted what to follow is typically a rhyolite dome rich in crystals due to slow cooling of the magma; this event makes it clear that the reason for lack of crystals in the obsidian are due to being erupted at a temperature greater than the final rhyolite magma
As the rock heats, decompresses, or is infused with water, the minerals with the lowest melting point (more felsic) melt first and begin to move away from the source rock, so a magma is always somewhat more felsic than its source
