Tachylite

(重定向自Tachylyte)
Basaltic glass in thin section, plane light top; cross-polarized light below
Flaked stone artefacts from Australia, made of tachylite

Tachylite (also spelled tachylyte) is a vitreous form of basaltic volcanic glass. This "glass" is formed naturally by the rapid cooling of molten basalt. It is a basic type of igneous rock that is decomposable by acids and readily fusible. The color is a black or dark-brown, and it has a greasy-looking, resinous luster. It is very brittle and occurs in dikes, veins and intrusive masses. The word originates from the Greek takhus meaning swift.
