| 摘 要： | 为了明确鄂尔多斯南缘平凉期沉积相类型及展布情况,在对研究区野外剖面实地踏勘的基础上,对不同的岩石类型、沉积构造及生物组合进行研究,总结归纳出了鄂尔多斯南缘平凉期的沉积相类型,主要有开阔海台地相、台地边缘滩礁相、台地前缘斜坡相、以及深水斜坡—海槽相。在次基础上,绘制了平凉期鄂尔多斯南缘的沉积相分布图,确定了各个相带的空间...

| Abstract: | Based on the reconnaissance work and study of rock type,sedimentary structure and assemblage biozone,the types of sedimentary facies are defined,which contain open marine platform facies,platform edge shallow and reef facies,platform front clinothem facies and deep water clinothem-trench facies.The distribution graph of sedimentary facies is drafted,which defined the distribution range of all the facies.At last,the sedimentation model is summaried,and the background of deposit evolution is analysised.Some g... |
