本文所称南方煤田,是指我国南方的苏、浙、皖、闽、鄂、湘、赣、粤、桂九省、区的诸煤田而言,但苏北和皖北各大煤田不在本文讨论范围以内。全区面积约一百三十万平方公里,占全国总面积的百分之十四左右。在这里,分布着大大小小五十个煤田,其中除鄂西的荆当、秭归和皖南的怀宿、巢县少数煤田位于长江北岸而外,其余均在长江以南。南方煤炭资源的分布,既受成煤前的基底构造和成煤时的构造运动控制,又为成煤后的构造运动所改造。因此,要揭示煤炭资源分布同构造运动发生、发展间的内在联系,就需从煤田的形成和改造两方面进行研究。
The southern coalfields referred to in this paper refer to the coalfields in the provinces of Jiangsu, Zhejiang, Anhui, Fujian, Hubei, Hunan, Jiangxi, Guangdong and Guangxi in the south of our country, but the major coal fields in northern Jiangsu and northern Anhui are not discussed in this article Within the range. The entire area is about 1.3 million square kilometers, accounting for about 14% of the total area of the country. Here, 50 large and small coal fields are distributed. Among them, except for the Jingdi in western Hubei, Zaiigui and Huai places in Wannan, a few coalfields in Chao County are located on the north bank of the Yangtze River and the rest are south of the Yangtze River. The distribution of coal resources in the South is controlled both by the basement structure before coal formation and tectonic movement during coal formation and also by the tectonic movement after coal formation. Therefore, to reveal the distribution of coal resources with the tectonic movement occurs, the development of the internal link between the need to study the formation and transformation of coal from two aspects.
