N2 - The blueschists, discovered in the Gangmar-Taoxing Co area, central Qiangtang, Northern Tibet, consist of glaucophane, ferroglaucophane, crossite, phengite, actinolite, epidote, chlorite, calcite, sphene, rutite, etc., with the metamorphic temperature 400°C ±, and pressure 7kbar ±, which demonstrates there occurred a high pressure metamorphic belt. The 39Ar - 40Ar dating from the glaucophane yields 275 - 287Ma, which comprehends the metamorphism being related to subduction of the Paleotethyan ocean. It is thought to extend southeastwards and link up with the Lancangjiang high pressure metamorphic belt in west Yunnan, constituting a very important tectonic boundary between Gondwana and Euroasia continents.
