川东地区三叠纪富钾卤水资源是近年来我国钾盐寻找主要的远景区之一，近年来成为富钾卤水研究和前期勘探的重点。该区域位于四川东部宣汉地段，属大巴山与华蓥山构造人字形交接的西区复合部位。通过对测区内的大地电磁数据进行二维反演，对比不同模型的正演模拟，分析该地区的岩矿石电磁特征属性和所测得的电磁曲线，并对该地区的岩矿石进行了岩石物性分析，结合地质、古水文地质以及测井资料等，初步圈定了四川东部富钾卤水的纵向分布层位和分布特征以及横向上的变化等，为下一步工作中富钾卤水资源量估算奠定了基础。

In recent years,it is one of the main prospect areas in Triassic brine rich in potassium resources in the east of Si-huan Basin,which is an important region in recent years of the study and exploration of brine rich in potassium.This area is lo-cated in the Xuanhan county of Sichuan eastern,where is the west composite part of Dabashan mountain and Huayingshan tec-tonic herringbone area.According to the two-dimensional inverse of magnetotelluric,comparing with the different forward modeling,and analyzing electromagnetic characteristic properties of rock ore and the measured electromagnetic curve in this re-gion.At the same time,analyzing the physical properties of rock,combining with the geology,paleo hydrogeology and logging information,we preliminary delineate the potassium longitudinal distribution of strata,distribution characteristics and lateral changes,etc,in the east of Sichuan basin,and work for the next step to do the basic for the rich brine potassium resources es-timation .
