متن کاملA 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...
متن کاملAssuring Sustainable Economic Benefit for Farmers by Using Ground Water in Semi-Arid, Hard Rock Areas in India & the Role of UNESCO-IUGS-IGCP Project 523

Rains in Monsoon season from June to September, provide the main source of water but they last only for four months and the rest of the year is dry in ...
