This material is called "scoria" by some, but bears no relationship to volcanic processes producing scoria rock. The portion of the mine to the south is a scraper-shovel-truck operation while the mine area to the north is a dragline operation to date.
It is actually a material called Scoria Glass which is a by-product of the mining industry. More specifically it is a black (super dark green) glassy material from the first smelt of metal ore. For as long as people of the craft can remeer we have used Cornish Obsidian as a perfect replacement for Jet, Schorl and especially Obsidian.

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chaer below the surface. Earth''s volcanoes occur because its crust is broken into 17 major, rigid tectonic plates that float on a hotter, softer layer in its mantle. Therefore, on Earth
Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts.
