Pseudotachylite in the Agto area

Abstract

During field work in high-metamorphic complexes of the Agto area glassy pseudotachylite (in the sense of Philpotts, 1964) was found in several localities. The pseudotachylite is restricted to a few of the major movement-zones. These zones form rectilinear depressions which are very distinct on areal photographs and some are inferred to be of regional importance.
