| 摘 要： | 安徽明光石坝地区新近纪地层划分方案不一 ,通过地层剖面的测制和利用构造—岩性—岩相法进行地质填图 ,系统采集 ESR测年样 ,并结合区域对比 ,自下而上将该区新近纪地层划分为下草湾组、桂五组。其中下草湾组为原“下草湾组”的下段 ,时代为中新世 ;桂五组则包括原“下草湾组”的上段 ,时代为上新世。

| Abstract: | There are many different plans for the division of the Neogene strata in the Shiba area of Mingguang, Anhui. In this paper the strata are divided into ascendingly the Neogene Xiacaowan and Guiwu Formations by using structure lithology lithofacies method, systematic collection of samples for ESR dating as well as regional correlation. The Xiacaowan Formation is the lower part of the former Xiacaowan Formation and considered to be of Miocene age. The Guiwu Formation contains the upper part of the former Xiacaowan Formation and considered to be of Pliocene age. |
