Abstract
WORK on the Isortoq granulite facies rocks of the Nagssugtôqidian mobile belt1 in West Greenland has revealed an area where the rocks show features believed to be caused by shock metamorphism, while in neighbouring areas small veins of glass-mylonite (hyalomylonite) have been generated in pre-existing regional thrust zones.
