Abstract

The history of this block of low-grade metamorphic sediments begins with sedimentation, followed by strong deformation. Intrusion of spessartite dykes then took place, after which movement was resumed with deformation of the spessartites. Next followed jointing and the production of peculiar structures here called joint-drags. The final episode was one of block faulting, to which the formation of the Muness Phyllite Block itself as a graben is due.
