摘要
Abstract
Located on the Shangdan tectonic zone, the Danfeng Group complex in the East Qinling mountains was on whole formed in Newproterozoic (1?000～800Ma). Petrogeochemical characterisitics of metabasic volcanic rocks within the complex of this group show that, instead of being ophiolite, they are island_arc type volcanic rocks formed in an active epicontinental paleoisland_arc tectonic environment under the plate tectonic system of Newproterozoic main orogenic epoch in Qinling orogenic belt.关键词
