摘要
为了了解东台吉乃尔湖西段钾矿特征,结合区内2个钻孔资料,介绍了区域地质和研究区地质、区域及区内矿产赋存状况、含水层厚度、富水特征、卤水化学成分,成矿地层主要为中、下更新统。分析了东台吉乃尔湖西段钾、锂含量,结果表明KCl、LiCl含量低,在2000~2500 m以粉砂岩、细砂岩为介质的含水层段钾、锂、硼的含量高于900 m以浅的含水层段。钾矿的形成及影响因素和西台湖—东台湖间隐伏背斜有着密切的关系。
In order to understand the characteristics of potash deposits in the western section of Dongtai Jinel Lake,combined with the data of two boreholes in the area,this paper introduces the regional geology and the geology of the study area,the occurrence of mineral resources in the region and the area,the thickness of aquifer,the characteristics of rich water and the chemical composition of brine.The ore-forming strata are mainly middle and lower Pleistocene.The contents of potassium and lithium in the western section of Dongtai jinel Lake are analyzed.The results show that the contents of KCl and LiCl are low,and the contents of potassium,lithium and boron in the aquifer section with siltstone and fine sandstone as medium are higher than those in the shallow aquifer section of 900 m from 2000 m to 2500 m.The formation and influencing factors of potash deposits are closely related to the concealed anticline between Xitai Lake and Dongtai Lake.
