Scoria. Scoria or cinder is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob and cooled in the air to form discrete grains called clasts. [1] [2] It is typically dark in color (brown, black or purplish-red), and basaltic or andesitic in composition.
Around 360 oreum are distributed throughout Jeju. Their formation and preservation are due in part to the high permeability of the volcanic rock. [1]Magma erupting under pressure can solidify into scoria, which may fall and pile up around a crater to form circular and elliptical scoria cones and cinder cones.

[5] [6] Scoria differs from pumice in being denser. With larger vesicles and thicker vesicle walls, scoria sinks rapidly. The difference is the result of the lower viscosity of the magma that forms scoria. When larger amounts of gas are present, the result is a finer-grained variety of pumice known as pumicite.
