江西晚三叠世安源煤系沉积特征及沉积环境探讨

Probe into Depositional Characteristics and Environment of Late Triassic Anyuan Coal Measures,Jiangxi

江西省晚三叠世安源煤系,为江西省主要含煤地层之一,其煤种为烟煤,煤质好且为较好的动力用煤。然而,由于煤矿资源减少,造成我省乃至全国动力用煤的紧张状况,在一定程度上制约了经济的发展。通过对江西晚三叠世安源煤系(组)的沉积特征和沉积环境的分析,指出了研究区安源煤系的分布状况和赋存特征,对寻找后续煤炭资源具有一定的指导意义。

Late Triassic Anyuan coal measures, is one of main coal-bearing strata in Jiangxi Province. The high quality bituminous coal is good for power-station. But because of decreasing coal resources, made power-station coal in short supply in the province and even in whole country, and restricted economic development. Through studies on depositional features and environment of Late Triassic Anyuan Formation （coal measures）, pointed out the coal measures distribution and hosting features in study areas. It has certain guiding significance for subsequent coal resource looking.
