安徽巢湖麒麟山剖面中、晚石炭世碳酸盐岩地层发育较好 ,沉积类型多样 ,成岩特征明显 ,是研究碳酸盐岩沉积及成岩作用的理想剖面之一。文章采用微相分析的方法 ,对该剖面碳酸盐岩的生物组合、颗粒成分、基质类型及其结构等微相特征做了深入研究 ,将该剖面的沉积归纳为 7种微相类型 ,并认为该剖面中、上石炭统属于浅海碳酸盐台地相产物。
In Qilinshan section of Chaohu Lake in Anhui Province, Late Carboniferous carbonate rocks developed well, with various sedimentary types and obvious diagenetic features. It is one of the ideal sections to study the sedimentation and diagenesis of carbonate rocks. In this paper, micro-facies analysis is used to study the microfacies characteristics of carbonate assemblages such as bio-assemblage, grain composition, matrix type and structure of this section. The sedimentary facies of this section are classified into seven types of microfacies It is considered that the Upper Carboniferous belonged to the shallow marine carbonate platform in this section.
