摘要
含盐系由五个含盐组构成,赋有相应盐层(S_1—S_5)和多层钾盐(K_1—K_8),盐层空间分布受基底构造、古地形、淡水补给状况(乌图美仁河、托拉海河、格尔木河、清水河)控制。固体钾矿层限于达布逊湖,察尔汗区段,低品级。液体钾矿层分层性明显,各品级矿呈多层或单层结构,全境以 a 级矿矿层为主体。
In this paper,distribution regularity of the saline beds and potash ore beds in theQarhan saline lake is discussed on the basis of the field investigations and synthetic researches.TheQarhan saline series is mainly composed of five saline formations,in which several saline beds(S_1—S_5)and multiple potash ore beds(K_1—K_8)occur.The spacial distribution of saline beds is controlled by some factors,such as basement structures,palaeogeomorphic features and the recharge condition of fresh Water(Urt Moron,Toroi,Golumd,Qing-shui rivers).The solid potash ore beds are limited to Dabsan lake and Qarhan sector,with the grade in the orebeds being lower.The layering is very obvious in the liquid potash ore beds,and the ore beds of various grades takemultiple-or single-layer occurrences,the ore beds in the whole ore area occur mainly as‘a’grade.
