Scoria

Igneous Rocks

Scoria, also called volcanic cinder, is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob that cools in the air into discrete grains called clasts. It is riddled with macroscopic ellipsoidal vesicles, gas bubbles that give it a low density, though unlike pumice it typically sinks in water.

Caused By

Volcanism, Processes

Caused by volcanic eruption: scoria forms from molten material ejected from a volcano and cooled in air. Fresh quote fetched live: the registered scoria-wikipedia quote covers vesicle texture, not origin.
