本文阐述了福建大坑煤田的地层层序。大坑组中段以往被置于晓三叠世。根据近期对其所含的叶肢介,瓣鳃类和植物化石的研究,其时代应属于早侏罗世。大坑组的上段和下段是由于构造运动的结果。被置为上下关系。事实上,根据岩性和植物群的特征,这两个段实际为同一地层,时代属晚三叠世。由此我们可以推论,在大坑和鲤鱼地区可能成为寻找新煤田的远景区。
This paper describes the stratigraphic sequence of the Dakeng coalfield in Fujian Province. The middle part of the Tai Hang Formation was previously located in the Xiao Triassic. According to its recent study on leaf-limbs, flap gills and plant fossils contained therein, its era should belong to the Early Jurassic. The upper and lower segments of the Tai Hang Formation are the result of tectonic movement. Is set up and down relations. In fact, according to the characteristics of lithology and flora, these two segments are in fact the same strata and belong to the Late Triassic. From this we can conclude that the Tai Hang and Lei Yue areas may be the prospect of finding new coal fields.
