伊犁盆地南缘侏罗系水西沟群粘土矿物成因简析

Brief Analysis of Cause of Clay Minerals in Southern Margin of Jurassic Shuixigou Group

粘土矿物是砂岩中最重要的胶结物与填隙物,它们在砂岩中的含量、产状以及矿物组成,对砂岩的孔隙结构、渗透性能都有十分重要的意义。采用带能谱仪的扫描电镜镜下观察、X射线衍射等手段,以伊犁盆地南缘侏罗系水西沟群为目的层,分析研究粘土矿物特征、形成机制。

The clay minerals are the most important cements and interstitials material in the sandstone, their content in the sandstone, occurrence ＆ mineral composition, pore structure of sandstone and permeability have great significance. Using scanning electron microscopy with energy dispersive spectroscopy, X-ray diffraction microscopy means, the authors analyze characteristics and formation mechanisms of clay minerals, the target layer. taking southern margin of Jurassic Shuixigou group as
