广东连州地区下石炭统连县组主要由深灰色中厚层状白云质灰岩与白云岩组成,化石丰富,分布广泛。通过对野外路线调查剖面测制及前人研究成果的收集,根据岩性、厚度及含化石情况对区域空间分布规律的分析,探讨连州地区连县组岩性组合特征得知区内中部及东北部含白云质较高,西北部含硅质及泥质较高;厚度由中部向北东及北西方向由薄逐渐增厚。为邻区开展野外调查及地层对比打下了坚实基础。
The Lower Carboniferous Lianxian Formation in Lianzhou, Guangdong Province consists mainly of dark gray, medium-thick layer dolomitic limestone and dolomite, with abundant fossils and widely distributed. Based on the investigation of the profile of field survey and the collection of previous research results, the spatial distribution of the area is analyzed according to lithology, thickness and fossils. The characteristics of lithology in Lianxian Formation in Lianzhou area are also discussed. In the northeast, there is a higher content of dolomite, a higher content of siliceous and argillaceous in the northwest, and a thicker thickness from the middle to the north east and north west. It has laid a solid foundation for conducting field surveys and stratigraphic comparisons in neighboring areas.
