Abstract
Pseudotachylite is distinguished from ultramylonite by the fusion products glass, vesicles, and microlites of intermediate to high temperature feldspar. Pseudotachylite is restricted to quartz-bearing rocks, probably because of mechanical, rather than melting properties of quartz. Fusion is total, not partial, and results from faulting where temperature is already high as a result of igneous activity or deep burial. Relative to country rocks, pseudotachylite is lower in soda and lime and higher in potash and silica. The gas phase is mostly water and carbon dioxide, but contains some iron and possibly silica. Four new analyses of pseudotachylite and two of jotunite wallrocks are given.
