摘 要: | 一、区域地质概况浪平碳酸盐台地位于桂西北田林县与乐业县境内,在区域构造上位于华南海西部南盘江区域内。根据我院碳酸盐岩研究室的研究,华南海在早古生代末期位于大陆边缘,海西期时受东南库拉板块俯冲以及西部特提斯海北支洋壳分裂的影响,区域上形成北东与北西向两组断裂系统,从而使海区进入陆缘断陷海盆地发育阶段。断裂活动把早古生代的基底切割成网状分布的狭长形断堑以及由其所围限的块状断垒。

Abstract: | The Longping carbonate platform is located in the N anpan River area in the w estern part of the continental m argin fault basin in South China. In this area, it is a smaller one in a series of isolated carbonate platforms. It is surrounded by the NW and NE trench-rift of the graben type. The platforms are formed by the rising of horst fault. In the Carboniferous epoch, there was a successional carbonate deposits area. T he bryozoan-coral reef is located in the southern tip of the plat- form--sear Gan Dong Zi. |
