ABSTRACT: Paleogeography and Tectonic Control on Permo-Carboniferous Coal Deposition in the North and South China Plates

Liu Guanghua

The most important coal deposits in China were laid down in the Permo-Carboniferous period. The deposits of North and South China differ markedly in their coal quality, coal geometry, and in their environment of deposition. This is related in part to the fact that at the time of deposition the North and South China plates were distinct entities, separated by a paleo-Tethyan sea. Owing to their relative positions with respect to paleolatitudes, the two plates were submitted to climatic extremes from moist tropical to arid subtropical at different times during the Permo-Carboniferous.

The two plates also experienced various degrees of tectonism at different times in their history. For this reason the interfaces of tectonism and climate resulted in differing regimes of coal development in both plates. In the north, the early coal deposition was influenced by the effects of collision with the Siberia Plate; in the south, deposition was controlled essentially by plate marginal movements associated with back arc extension. All of this is reflected in the seam geometry and quality and, hence, the economic viability of these coal deposits.
