摘要
在贵阳乌当断层南北两侧，下石炭统九架炉组、祥摆组和旧司组的分布和沉积特征存在明显的变化，九架炉组仅分布于乌当断层北西侧，祥摆组由北向南的沉积环境由泻湖相向浅海相呈有规律的变化，旧司组则仅在乌当断层南侧分布。这些地层的分布规律、沉积环境的变化说明了乌当断层为黔中隆起南侧边缘断层，且该断层自早古生代形成后，晚古生代仍有活动。
Along the south and the north of the Wudang fault,there are apparent changes in the distribution and depositional characters of the Jiujialu,the Xiangbai and the Jiusi formations (Lower Carboniferous).The Jiujialu formation distributed only in the north of the Wudang fault.From north to south,the deposition environment of the Xiangbai formation changed regularly from the lagoon to the shallow sea facies. The Jiusi formatoin distributed only in the south of the Wudang Fault.The stratigraphic distribution and the various depositional environment showed that it was the Wudang fault that was the southern boundary of the Middle Guizhou Uplift,and the fault formed is the Early Palaeozoic and still active in the Late Palaeozoic.
