| 摘 要： | 华蓥山北倾没端地区石炭系地层是发育在志留系侵蚀面上的一套碳酸盐台地相沉积,主要为晶粒白云岩和颗粒白云岩。根据对其沉积物特征、沉积组合和测井相的综合分析,认为研究区主要发育有两种沉积相,三种沉积亚相,并可细分为膏云坪、膏盐潮池、生屑颗粒滩、鲕粒颗粒滩、滩间泻湖等微相。在石炭系黄龙组沉积早期区内主要处于干燥炎热的蒸发台地环境,随着海水的缓慢侵入以及气候的变化,黄龙组沉积晚期逐渐形成了局限台地相的沉积格局。

| Abstract: | The Carboniferous System at the north pitching end of the Huayingshan anticline is a carbonate platform deposit which covers unconformably on the Silurian.This paper divides it into 2 sedimentary facies,3 sub-facies and 5 microfacies.The Middle Carboniferous Huanglong Formation was deposited in evaporate platform environment in the early and in restricted platform in the late. |
