what is the specific gravity of scoria

Scoria - chemeurope

Scoria is light as a result of numerous macroscopic ellipsoidal vesicles, but most scoria has a specific gravity greater than 1, and sinks in water. The vesicularity results from the exsolution of magmatic volatiles prior to chilling.

Available USA resources are estimated to be about 3 cubic miles (12 km 3) of scoria (based in part on Higgs (1949), about 9000 million short tons (82×10 9 t)). At a projected level of 3 million short tons (27×10 6 t) annually, scoria production for more than 1000 years can be adequately accommodated within this total resource.

1.3 Scoria and Volcanic Cinder. Scoria (larger than 1 in (25 cm) in size) and volcanic cinder (smaller) are cellular, frothy products of explosive mafic volcanism—erupted as bombs, blocks, lapilli, volcanic gravel, or lava flows. Much of the material is lava forcefully ejected from the vent, vesiculating as volcanic gases expand and are ...
