PSEUDOTACHYLYTE

Domain	Definition
Mining	A. A dense rock produced in the compression and shear associated with intense fault movements, involving extreme mylonitization and/or partial melting. Similar rocks, such as some of the Sudbury breccias, contain shock-metamorphic effects and may be injection breccias emplaced in fractures formed during meteoric impact. CF:ultramylonite b. A dark gray or black rock that externally resembles tachylyte and that typically occurs in irregularly branching veins. The material carries fragmental clasts of adjacent rock units, and shows evidence of having been at high temperature. Miarolitic and spherulitic crystallization has sometimes taken place in the extremely dense devitrified base. Some pseudotachylyte has behaved like an intrusive and has no structuresobviously related to local crushing. (references)
