| 摘 要： | 通过对中昆仑地区各时期沉积特征的分析，认为泥盆纪至古近纪可划分为两大沉积环境，即陆相沉积环境和海相沉积环境。陆相沉积环境主要分布于侏罗纪至古近纪，海相沉积分布于泥盆纪至三叠纪时期，共划分为5相和若干于沉积类型。该区在历史的长河中经历了原特提斯洋的扩展和封闭造陆阶段；南昆仑洋的形成和造山阶段；前陆盆地形成和发展阶段，以及陆相的山盆发展阶段。

| Abstract: | By analysis the sedimentary characters of middle Kunlun area in different period,it's thought that Devonian to Paleogenein can be divided into two sedimentary environments: continental facies and sea facies.Continental facies maily distributed in Jurissic to Paleogenein,sea facies mainly distributed in Devonian to Triassic,formed 5 facies and some sedimentary environments.This area experienced the enlargement of former Thetis Ocean and closed epeirogenetic stage;the formation of south Kunlun Ocean and epeir... |
