四川峨眉龙门洞剖面位于峨眉县城以西约八公里处。剖面分布在龙门洞口至峨眉电站一带,全长约三公里。过去成都地矿所、地质局207队等单位先后对此剖面做过工作。由于该剖面的岩层出露良好,沉积构造标志清楚,近年来被公认为是研究沉积相的参观剖面。为了进一步研究飞仙关组的沉积环境和建立沉积模式,我们于1981年比较系统地测制了精度为1:100的沉积相剖面。其剖面的特征及沉积相的划分如表1所示。
Sichuan Emei Longmen cave profile is located about 8 kilometers west of Emei county. Profile distribution in the Longmen hole to Emei power station area, a total length of about three kilometers. In the past Chengdu Institute of Geology and Mineral Resources, Geological Bureau 207 teams and other units have worked on this profile. Because of the well-exposed strata of the section and the clear sign of sedimentary structure, it has been recognized as a study section of sedimentary facies in recent years. In order to further study the sedimentary environment and establish the sedimentary model of Feixianguan Formation, we systematically measured the sedimentary facies profile with a precision of 1: 100 in 1981. The characteristics of the section and the division of sedimentary facies are shown in Table 1.
