| Abstract: | The Presinian System in the area of Xiaoshan-Fuyang is composed of the marginal island arc volcanic rocks of Shuangxiwn Group in Middle Proterozoic Era and, the retroarc basin deposits and bimodal continental volcanic rocks of Heshangzheng Group. Qingbaikou Period in Late Proterozoic Era. The Shengong Movement in late Middle Proterozoic Era was strong and the superimposed fold of Junning Movement in late Qingbaikou Period was clear. The profiles are continuous and intact, and the geological phenomena are diversified. They are important Stratotype profiles in the Southern part of China. |
