| 摘 要： | 黔南桂西地区(东经105°-107°,北纬24°20′-26°40′)地跨扬子准地台和加里东褶皱带两个一级大地构造单元。早三叠世时该区由西北向东南,从浅海沉积环境变为深海沉积环境。沿贵州福泉、惠水、紫云、贞丰、安龙以及广西隆林、西林一带长约400公里、宽25-70公里的“S”形狭长地区是分隔浅海、深海沉积环境的古大陆斜坡。该区的沉积相带划分如图1。各相带的主要沉积特征见表1。斜坡相带沉积物主要为低密度浊流和远洋悬浮沉积的暗色薄板状泥晶灰岩,具重力滑移构造(图版Ⅰ,6)。

| Abstract: | In Early Triassic sea area in Southern Guizhou and Western Guangxi，there exis- ted a carbonate sedimentary pattern of continental slope without bioherm,which was about 400 km long，25-70 km wide and roughly speard with a "S" pattern from nor- th-east to south-west. |
