根据野外露头对铜陵地区的上石炭统进行了层序地层分析。上石炭统分为 A、B、C 3个沉积层序 ,分别相当于黄龙组的下部、中上部和船山组。其中层序 A、C属于 类层型界面 ,层序 B属于 类层型界面。与 类界面相比 , 类界面比较清晰易辨。区内缺乏低位域 ,层序由海侵体系域 (TST)和高位域 (HST)组成 ,并且海侵体系域不甚发育 ,高位域组成了层序的主体。海平面变化控制了层序的演变 ,但局部构造沉降则影响了沉积物的厚度
Based on the outcrops of the outcrop, stratigraphic stratigraphy was analyzed on Upper Carboniferous in Tongling area. The Upper Carboniferous is divided into three sedimentary sequences of A, B and C, corresponding to the lower part, the upper part and the Chuanshan Formation of the Huanglong Formation, respectively. Among them, the sequence A and C belong to the class-type interface, and the sequence B belongs to the class-type interface. Compared with the class interface, the class interface is relatively clear and legible. Lack of low-level domain, the sequence of transgressive system tract (TST) and high-level domain (HST) composition, and the transgressive system tract less developed, the high-level domain constitutes the main body of the sequence. Changes in sea level control the evolution of the sequence, but local structural subsidence affects the thickness of sediments
