应用煤地质学和沉积学相结合的的理论和方法，揭示了南华北晚石炭世地层中存在的异地煤，根据煤层顶、底板和煤层本身的特征以及煤层在区域上分布的特点，可以看出，这些异地煤的形成，是由于热带－亚热带频繁的风暴作用侵蚀滨海泥炭沼泽的结果。强烈的风暴作用，不仅通过风暴上升流侵蚀改造泥炭层，而且还通过风暴回流将部分泥炭物质搬运到浅海环境再沉积，从而在泥炭沼泽内和浅海海底两种场所形成两种不同类型的异地煤。
Based on the theory and method of combining coal geology and sedimentology, the different coal in Late Carboniferous strata of South China is revealed. According to the characteristics of coal seam roof, floor and coal seam itself and the distribution of coal seam in the area, Out of these, the formation of these off-site coal is the result of erosion of coastal peat swamps due to frequent storm-subtropical storm action. The strong storms caused not only alteration of the peat layer by storm upwelling erosion but also the removal of part of the peat material to the shallow sea environment by storm backwash to form two different types of off-site coal in both the peat swamp and the shallow sea floor .
