摘要

A coral fossil Chatetes（Boswellia） heritschi Sokolov was discovered for the first time in the Zhanjin Group along the geological section between Dashahe and Guoganjianianshan in middle Qiangtang region. This discovery provides evidence of the Late Carboniferous biological age for the Zhanjin Group. The results suggested that the middle Qiangtang tectonic zone of Karakorum-Longmucuo-Shuanghu is biologically a mixed zone of Gondwana and Tethys biota in Carboniferous and Permian period, and there exists no obvious boundary of the biological region. It is thus inferred that the ocean basin represented by the Longmucuo-Shuanghu ophiolitic zone was a small marginal basin in southern Tethyan archipelago.
