| 摘 要： | 在分析滇西南晚第三纪区域构造背景的基础上，阐述了含煤盆地的形成，按其成因将盆地分为剪切盆地、剪切－拉张盆地和拉分盆地３种类型。盆地为冲积扇、湖泊、沼泽和河流相沉积物所充填，其演化过程可分为５个阶段：强烈沉陷阶段、稳定发展阶段、萎缩封闭阶段、剥蚀阶段和再沉陷阶段。

| Abstract: | Based on analysis of the late tertiary regional tectonics in southwest Yunnan, the formation of coal-bearing basin is studied. They fall into three genetic types: shear, shear-tensile, and pullapart basins, being filled by fan, lacustrine, swampy and fluvial deposits. Their evolution can be divided into five stages, namely, strong subsidence, stable sag, shrinking-close, denudation and re-subsidence. |
