| 摘 要： | 在层序地层学研究的基础上,对柴达木盆地红柳泉-跃东地区第三系中新统上干柴沟组进行了详细的沉积相分析,揭示了上干柴沟组发育的冲积扇相、扇三角洲相、辫状河三角洲相、湖泊相、浊积相等几种类型沉积相的特征。以识别出的三个三级层序为单位,详细分析了层序格架内沉积相的平面展布特征,总结了由于构造抬升造成的上干柴沟组湖盆演化及沉积中心东迁的规律。结合物源、构造、气候等因素分析了沉积相展布的控制因素。

| Abstract: | Based on sequence stratigraphic research,depositional facies of the upper Ganchaigou formation of Hongliuquan-yuedong area has been studied carefully.It comprises alluvial fan facies,fan-delta facies,braided stream delta facies,lacustrine facies,turbidite facies,etc.In the three Third-order sequences identified,the distribution of depositional facies are discussed,and the lake basin evolution and eastward movement caused by tectonic uplift are speculated.The control factor of the depositional facies exhibition has been simply analyzed. |
