Abstract
Blueschists are considered the mark of plate tectonic boundary in the Gangmar-Taoxing Co area, central Qiangtang, Tibet. Based on geochemical characteristics of major, trace and rare earth elements and the geochemical diagram, the protolith of blueschists belongs to alkali basalt that is a skin to intraplate ocean island basalts, and formed on seamount-like structures under an intraplate plume. Together with the geological features, it shows that it presents a Palaeo-Tethyan ocean in the central Qiangtang area. Therefore, the area may represent the boundary between Gondwana and Laurasia continents during the Late Paleozoic period.
