太行山阜平隆起南部早前寒武系划分及其形成构造环境

THE EARLY PRECAMBRIAN SYSTEM SUBDIVISION ANDTECTONIC ENVIRONMENT OF ITS FORMATION INTHE SOUTHERN PART OF THE FUPING UPLIFTON THE TAIHANG MOUNTAINS

太行山阜平隆起南部早前寒武系自下而上可划分为:太古宙阜平群、蛟潭庄群、龙泉关群,早元古宙五台群、滹沱群。各岩群之间都属不整合接触。分别代表了太古宙的陆核发展及地块形成和早元古宙的裂谷构造等大地构造环境。

The southern part of the Fuping uplift is located in the middle part of Tai-hang mountains. There might be five unconformities existing in the Early Pre-cambrian system,and then it could be subdivided into five groups,that is Fuping Group, Jiaotanzhuang Group, Longquanguan Group of the Archean, and Wutai Group and Hutuo Group of the Early Proterozoic. They indicate that the Archeozoic tectonic environment is continental nucleus development and crustal block formation, and the Early Proterozoic tectonic environment is represented as rift.
