湘南早石炭世含煤沉积,发育普遍,分布很广(图1),约有850平方公里,占含煤面积的70％。目前各矿区、地段作过一些矿点检查、踏勘或普查找煤等地表工作,积累了一些实际资料。但都没有进行过勘探工作,研究程度较低。含煤地层的古生物组合、岩性、岩相特征以及含煤性等缺乏比较全面的认识。为了扩大煤炭资源,我们收集了现有资料,初步进行分析整理,为今后普查勘探和科研工作提供参考。
Early Carboniferous coal deposits in southern Hunan are widespread and widely distributed (Figure 1), covering an area of 850 km 2, accounting for 70% of the coal-bearing area. At present, all the mines and lots have done some mine spot inspections, reconnaissance or census and coal mining and other surface surveys and have accumulated some actual data. However, none of the exploration work has been carried out and the research level is relatively low. The paleontological assemblages, lithology, lithofacies characteristics and coal-bearing properties of coal-bearing strata lack a more comprehensive understanding. In order to expand the coal resources, we collected the existing information and conducted preliminary analysis and collation so as to provide reference for future general survey, exploration and scientific research.
