About ScoriaHide

Highly vesicular, basaltic glass

i. A bomb-size pyroclast that is irregular in form and generally very vesicular. In less restricted usage, a vesicular cindery crust on the surface of andesitic or basaltic lava, the vesicular nature of which is due to the escape of volcanic gases before solidification; it is usually heavier, darker, and more crystalline than pumice. The adj. form, scoriaceous, is usually applied to pyroclastic ejecta. Cinder is sometimes used synonymously.

ii. A local term for melted or partly melted rock (buchite) surrounding burned-out coal beds in the Western United States.
