摘要: 本文讨论了北碚地区下三叠统飞仙关组的沉积特征。以碳酸盐沉积为主体的堡岛系统,既类似于、又有别于陆源碎屑的堡岛系统。文中以较充足的资料论述碳酸盐堡岛的地貌单元、沉积组合、水动力条件等,为识别和划分古代碳酸盐堡岛的相带提供一个实例。

Abstract:

The sedimentary characteristics of Feixian Guan Formation in Lower Trassic System, Beipei area,have been discussed in this paper. It is believed that the carbonate deposit-dominated barrier system is similar to, but different from the terrigenous barrier system. Information in the paper fully shows the distinguishing features of geomorphologic units, sediment assemblages, hydro-dynamic conditions of the carbonate barrier. The purpose of this paper is to provide an example for recognition and division of the ancient carbonate barrier.
