中国南部早石炭世聚煤期、聚煤区及有关含煤地层的划分与对比

华南下石炭统为中国南部地区的主要含煤地层之一。据其聚煤期的先后、含煤性及其工业可采煤层等不同因素,划分为Ⅰ、Ⅱ、Ⅲ、Ⅳ和Ⅴ聚煤期及8个聚煤区,并对有关存在争议地层的时空关系和化石带作了阐明。

THE DIVISION AND CORRELATION OF THE EARLY CARBONIFEROUS COAL-FORMING PERIODS,COAL-FORMING REGIONS AND COAL-BEARING STRATA IN SOUTHERN CHINA

The Lower Carboniferous is one of the main coal--bearing strata in southernChina, widely exposed in Hunan, Guangxi, Guangdong, Guizhou, Yunnan, Xizang(Tibet), Jiangxi, Zhejiang, Fujian, Jiangsu, Anhui and Hubei. On the basis of thehorizon of the coal--bearing strata, coal formation involves four coal--forming peri-ods (see Table 1). According to different coal-forming periods, coal--bearing natu-res, coal beds of commercial value and the number of coal layers, southern Chinamay be divided into eight coal--accumulating regions: the south--central Hunancoal--forming region, the northern Guangdong coal--forming region, the northernGuangxi coal-forming region,the southern Guizhou coal-forming region,the easternYunnan coal--forming region, the eastern Xizang coal-forming region, the easternGuangdong coal-forming region, and the south-central Jiangxi coal--forming region(see Table 1 and Fig.1).
