A proposal on behalf of the IUGS Subcommission on the Systematics of Metamorphic Rocks
This work presents the provisional results of the IUGS Subcommission on the Systematics of Metamorphic Rocks in respect to impactites. It is proposed to distinguish between impactites resulting from a single impact (e.g., at terrestrial impact craters) and those resulting from multiple impacts (e.g., lunar rocks or meteorites). The former are subdivided into two major groups: Proximal and dista...
