| 摘 要： | 本文根据岩性组合、剖面结构及与下伏地层接触关系等特征,认为贵州地区上白垩统茅台组是炎热干燥气候条件下,于燕山构造运动后未曾夷平基面上沉积的河湖相红色磨拉石建造,沉积盆地性质为山间盆地。茅台组现今的大范围零星散布,主要是喜马拉雅运动后遭受长期侵蚀剥蚀造成的。

| Abstract: | The Upper Cretaceous Maotai Formation strata are widespread in Guizhou except the Chishui region, with a maximum outcropped area of 25 km2 around the Yuqing region and a residual thickness of about 1440 m along the Rongjiang River. There is a unconformity between the Maotai Formation and underlying Qingbaikouan Xiajiang Group/Danzhou Group-Jurassic strata. Although commonly cropped out along the faults,the Maotai Formation strata are not controlled by the associated faults. Instead,they represent red fluvial-lacustrine molasse formations deposited above the unleveled surfaces in the intracontinental intermontane basins under the xerothermic climatic conditions from the Yanshanian movement onwards. |
