察尔汗盐湖察尔汗二级补给系统S3盐层晶间卤水中KCl的分异特征、富集规律及其成因

据ＫＣｌ含量的概率分布特征,晶间卤水分为７个总体。晶间卤水ＫＣｌ,在三级系统内水平分异有２种、剖面分异有５种,二级系统内水平分异呈环带状、剖面分异形式为三级系统内分异形式的组合,垂直分异有１３种;富集的总体为Ⅳ（ｋｃｌ）、Ⅲ（ｋｃｌ）用Ｖ（ｋｃｌ）、三级系统为（８）和（１０）号、部位为固相钾高含处;分异及富集的成因主要为晶间卤水的阶段性淡化。     

物探电法在锦州东港电力有限公司矿泉水水源地勘查的综合应用

锦州东港电力有限公司矿泉水水源地位于辽西中部断陷盆地锦州盆地的北端。地处中新生代上侏罗统及白垩系构成的对称向斜,NNE新华夏系断裂构造经由锦州盆地通过。工作区第四系覆盖6-14m,下伏孙家湾组(K2S)砂质泥岩、砂砾岩和义县组(K1y)火山碎屑岩、英安岩、安山岩及火山凝灰角砾岩。对该区进行地质水文资料综合分析的基础上,采用电阻率联合剖面、高密度电阻率法、电测深(电阻率、衰减时及极化率)多种物探电法综合勘查,确定断裂构造位置、产状及赋水性。经验证获得涌水量312t/d具有商业价值的矿泉水水源地。这一工作方法在辽西火山岩贫水区进行水资源勘查具有推广意义。
