| Abstract: | This paper suggests that the north part of East Qinling is the continental marginal terrain on South Sinokorean plate, which is the active con-tinental margin, characterized by double-lined island arc; the middle and south parts belong to the continental marginal terrain on north Yangtze plate, which is composed of two uplifts ( the north margin of the continental terrain and mid-Qinling microplate ) and one depression ( South Qinling basin ) , and the continental marginal terrain is the passive continental margin with weak magma and volcanic activities in Cambrian. |
