"Phacolite" Natural Recordings by Native Speakers
A phacolite is a type of fossilized inclusion, typically an opaque or translucent globular or oval-shaped body, found within the calcite of an alabaster or travertine deposit. Phacolithes are formed when a gas or liquid-filled cavity within the rock becomes replaced with calcium carbonate, usually during the process of dolomitization.
