Abstract

A Sm-Nd age of (228±42) Ma with initial εNd= −16.4 for the Renjiawan pyroxenite intrusion in the North Dabie terrane is reported. This age with another Sm-Nd age of (230 ±44) Ma for the Zhujiapu pyroxenite in the same terrane documents that the pyroxenite in the North Dabie terrane are formed during continental subduction time of the Yangtze craton in the Triassic.
