贵州独山-广西天峨地区中二叠世岩相古地理特征、相类型及几何形态

Lithofacies Palaeogeography Types,Facies and Geometry of Permian in Dushan of Guizhou and Tian'e of Guangxi

通过对贵州独山-广西天峨地区二叠系岩石地层、生物组合及沉积相的详细调查,重点收集中二叠时期岩性组合特征、生物组合特征和相等方面资料。从研究区该时期沉积旋回性、沉积相类型、岩相组合等进行研究,得出研究区为台地边缘沉积环境,并弄清了该台地边缘类型、几何形态及岩相古地理等。为区域上建立完善该时期的岩相古地理提供了宝贵的资料。

By detailed survey of lithostratigraphy, fossil assemblage and sedimentary facies, the informa- tion about lithology assemblage characteristic, fossil assemblage characteristic and facies are collected, The sedimentary cycle, sedimentary facies and lithology assemblage in the period of target area are studied, it＇ s known the target area is platform margin sedimentary environment, the type, geometry and lithofacies palaeo- geography are find out. It will afford beneficial information for perfecting the lithofacies palaeogeography in this period of this area.
