摘　　要：根据层序地层经典模式,运用地层垂向和横向综合对比的方法,在野外露头上对马角坝地区石炭纪地层进行了三级层序及沉积相上的分析。研究剖面划分为5个三级层序,其中1个Ⅰ型层序,4个Ⅱ型层序,认为马角坝地区石炭纪为一套局限—半局限、开阔台地沉积。Based on the classic model of sequence stratigraphy, this paper utilizes the vertical and horizontal comprehensive contrast method and conducts a third-order sequence and sedimentary facies analysis on Carboniferous stratum in the outcrop of Majiaoba District.The studied section is divided into 5 third-order sequences, of which one is Ⅰ type sequence and four are Ⅱ type sequences, and the Majiaoba District should be a confined, confined-half and open carbonate platform in Carboniferous period.
