摘要

ARGIN: auto 0cm" class=MsoNormal>an’,’serif’" lang=EN-US>Beishan group is a suit of strong metamorphic terrane which was suffered amphibolite facies main metamorphism and epidote-amphibolite facies fade metamorphism. According to characteristics of rock combination, the group can be divided into four formations. The first formation is mainly composed of amphibolite schist. The second formation is composed of gneiss interclated. The third formation is composed of quartz schist. The fourth formation’s parent rock is mature detrital rocks. The tectonic setting was in Early Proterozoic, early valley was developing, volcanoes break forth frequently, and detrital was sediment fleetly.amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
