| Abstract: | In the southeastern margin of Jiangnan geoanticline, occurs a lot of volcanic rocks of late Precambrian, e.g., Shuangxiwu Group in north Zhejiang, Dengshan Group in northeast JiangXi and Jingtan Group in south Anhui.It is demonstrated by up-to-date stratigraphic and chronological data that this volcanic sequence is of late Proterozoic in age and is stratigraphically comparable with Qing-baiko Group in north China.The sequence distributes along the southeast margin of Jiangnan geoanticline continuously and forms an integrate volcanic belt. |
