贵州晚二迭世含煤地层分布广泛,为该省主要的含煤建造。笔者近几年参与煤田预测工作,对其沉积特征,有一点粗浅的认识,并结合沉积古地理、古构造分析探讨其成煤规律。限于资料和水平,错误和不当之处,敬请批评指正。 下界 因黔西晚二迭世有多次大面积峨眉山玄武岩喷发,并在玄武岩内夹有含煤地层,产大羽羊齿植物群和腕足类 Lepetodus,Punctospirifer等化石,与其上含煤岩系生物面貌
Guizhou Late Permian coal-bearing strata are widely distributed and are the major coal-bearing constructions in the province. In recent years, the author has participated in the coalfield prediction work, and has a little superficial understanding of the sedimentary characteristics. Combining with the sedimentary paleogeography and palaeo-tectonic analysis, the authors discuss the law of coal formation. Limited to the information and level, error and inappropriate, please criticize correction. There are several large-scale emeishan basalt eruptions in the lower Permian in the lower reaches of western Qianxian in the lower boundary. Coal-bearing strata, Lepidodus punctatus and Punctospirifer,
