湘赣粤地区中生代含煤地层分布广泛,层序清楚,是华南主要含煤层位之一。30年代至今,尤其是60年代以来,许多单位或个人曾先后参与这一地层专题的研究,积累了丰富的资料。 湖南的中生代含煤地层大致可分四个沉积小区:湘东南区(向南和粤北连为一区),湘西南区(向西南和桂东北连为一区),湘东区(向东和江西中西部连为一区)和湘西区。这 The coal-bearing strata in Hunan, Jiangxi and Guangdong are widely distributed and well-defined, which is one of the major coal-bearing strata in South China. Since the 1930s, especially since the 1960s, many units or individuals have successively participated in the research of this stratigraphic topic and accumulated rich information. The Mesozoic coal-bearing strata in Hunan Province can be roughly divided into four sedimentary communities: southeastern Hunan (one area to the south and north to Guangdong), southwest Hunan (one area to the southwest and northeast of Guangxi), the eastern part of Xiangdong Central and Western Jiangxi Province as a district) and Western Hunan.
