摘要: 应用露头层序地层学的研究方法对桂中合山－来宾一带的合山组进行了系统研究,共识别出7个层序界面及这些界面所划分的6个层序,其中5个为1类层序,1个为Ⅱ类层序。层序发育具有被动大陆边缘型特征。台地区为浅水碳酸盐岩沉积,盆地区为严重欠补偿条件下的硅质岩沉积。Abstract: The present paper analyzes the upper Permian Heshan Formation from Heshan and Laibin areas incentral Guangxi by employing the study methods of outcrop sequence stratigraphy.In the Heshan Formation,7 sequence boundaries and 6 sequences defined by the boundaries are recognized.Among the 6 sequences,5 are attributed to type Ⅰ,and I to type Ⅱ.The sequences were formed in passive continentalmargin environment.Platform area was dominated by the sedimentation of the shallow carbonate sediments,and in the basin area the sediment of deep silicalite was developed in under-compensated conditions.
