| 摘 要： | “Qinling Group (?)” in Songshugou region in the north of the Shangdan Fault consists predominantly of amphibolite with or without garnet and amphibole-plagioclase gneiss and intercalated with lensiod blocks of garnet pyroxenite, where the famous Songshugou dunite body occurs (Fig. 1). Petrographic study reveals that garnet pyroxenite is the representative rock of early |
