Volcanoes produce igneous rocks such as granite, pumice, and obsidian. They all play an important factor in the world today.

Volcanism is the main process in forming extrusive igneous rocks.

I guess you could call it the "birth of a rock/mineral", erosion, deposition and metamorphosis would follow. If near a subduction zone it might be forced down and melt again.
