| 摘要： |
| 结合地质剖面和薄片鉴定结果等资料，对龙门山地区泥盆纪埃姆斯期—吉维特早期混合沉积的岩石学特征、沉积特征、沉积相类型进行详细分析。基于研究区陆源碎屑沉积和碳酸盐沉积的2种相模式，总结了各类混合沉积的产出部位、沉积特征，归纳出龙门山地区甘溪泥盆系的混合沉积相模式，认为主控因素是由区域母源性质、构造作用、相对海平面变化等因素构成。 |

| Abstract: |
| With the geological sections and identification results of thin section, the paper analyzed the petrologic characteristics, sedimentary features，and sedimentary facies type of mixed sedimentation in the Devonian Longmenshan Mountains from Emsian Stage to early Givetian Stage. Based on both facies mode of terrigenous clastic sediments and carbonate sediments in the study area, it summarizes the output sites and sedimentary characteristics of various mixed sedimentation, and the mixed sedimentation facies modes in the Devonian Longmenshan Mountains. It is found that the main controlling factors are regional source, tectonization, change of relative sea levels, etc. |
