摘要
对新近发现的新疆巴里坤大型膨润土矿进行了矿物学和地质特征研究，对该矿区791件膨润土样品进行了化学分析及数理统计。运用X射线衍射分析技术对其矿物组成进行了研究，查明新疆巴里坤大型膨润土矿蒙托石相对含量高，化学成分与国内其它膨润土矿相比差异明显，其中Na2O含量比较高，一般在4．20％～5．19％之间，Si和Al相对含量的变化是控制蒙脱石含量主要因素。从成矿地质背景分析，认为该矿床属火山沉积型矿床。
This paper studies systematically the mineralogy and geoloical characteristics of a large-scale bentonite ore deposit at Barkol, found recently in Xinjiang. Analysis and mathematical statistics were made of 791 ore samples, and Xray analysis was conducted of the mineral composition. The basic mineralogical characteristics and geological background of the bentonite deposit at Barkol, Xinjiang are described in the paper. So it is an important reference to explore bentonite mineral resources at Barkol, Xinjaing in the further.
