伊犁盆地ZK0161井褐煤中铀及其它元素的地球化学研究

Geochemistry study of its uranium and other element of brown coal of ZK0161 well in Yili Basin

用数理统计的方法,对伊犁盆地洪海沟ZK0161井的中下侏罗统11、12号煤层中的铀等59种常量、微量元素的地球化学行为进行了初步探讨。认为元素在灰分的分布和元素在内在水分及固定碳中的分布大体呈互为相反数关系,而和元素-挥发分相关系数则呈同步性变化。ZK0161井煤中U以后生铀为主,分别以可溶态和有机吸附态或结合态形式出现在12号煤和11号煤顶部的煤中内在水和煤有机质中。

The research of geochemistry of 59 kinds constant elements and trace elements in brown coal of ZK0161 well,which located at Honghaigou area in Yili Basin of Xinjiang Uyghur Autonomous Region,China,was completed by means of mathematical statistics methods.The results show that the correlation coefficients of ash-elements is each orther＇s opposite number with one of inherent moisture,and has synchronous changes with one of volatile-elements.Uranium in coal of ZK0161 well is mainly epigenetic one and may be respectively in the form of soluble existed in the internal water and organic absorbed or organic phase existed in organic matter on the top of No.11,12 coal seams.
