| 摘 要： | 千佛岩组发育冲积扇、曲流河、三角洲和湖泊沉积。曲流河发育洪泛平原和河道两个亚相;三角洲发育三角洲前缘、三角洲平原及前三角洲三个亚相;湖泊相则发育浅湖和滨湖亚相;冲积扇分出扇中和扇端两个亚相。龙门山系周期性推覆构造活动是川西前陆盆地沉积作用及层序发育的主控因素。

| Abstract: | In the region of Qianfoya Formation,alluvial fan,meander river,delta and lacustrine deposits are developed.And in the meander river area,there are 2 developed subfacies of flood plain and river channel.In the delta area,3 subfacies of delta front,delta plain and fore-delta.In the lacustrine facies area,there are 2 developed subfacies of shallow lake and lakeside.The alluvial fan facies can be divided into 2 subfacies of midfan and fan-end.The periodic nappe structure movement is the main control factor of s... |
