摘要
研究地层是有效寻找沉积矿产的重要基础,将龙永煤田内关于的层位及分带性与大区域上的相似层位作了对比,并论述了本煤田的特征与变迁的基本过程。最后,结合多年来的研究成果,就煤田内的产出情况,作了两点必要的说明。
Research of strata are important basis look for sedimentary deposits.Correlation on horizon and biozone of Permian Fusulina in Longyong coal-field with corresponding horizon in large area, and submitted features of fusulina and its basic process of changes in the coal-field.Finally,to do two points of necessary explanation aim at emergence of Fusulina in coalfield combine with research achievements since many years.
