摘要
鄂尔多斯盆地西缘为一走向南北的逆冲带，该带在地质构造上处于我国东部华北地台和西部地糟的交接地带，由于其特殊的大地构造位置，因此，形成了六盘山盆地和银川盆地两种不同性质的盆地．本文从这两个盆地的构造特征、形成及演化等几个方面分析、研究，认为六盘山盆地是一个中、新生代的挤压型盆地，银川盆地是一个先拉张后拉分的盆地．
he west margin of Eerduosi Basin is a south-north running thrust belt,where the North China platform in the east part of China and west geosyncline join together. Because of the distinctive tectonic location,two different types of basins formed:Liupanshan Basin and Yinchuan Basin. On the basis of the analysis and research of the tectonic characteristics, formation and evolution,it is deemed that Liupanshan Basin is a compression basin formed in Mesozoic era and Cenozoic era.and Yinchuan Basin is an early extension and late pull-apart basin in Cenozoic era.
