格尔木冲洪积扇地下水含有丰富的锶,地下水的水化学分带异于一般的冲洪积扇地下水水化学分带性规律。通过室内水-岩模拟试验以及野外监测,证明地下水及山区沉积物的物质不是基岩就地风化的产物。通过对区域地球化学背景及物质搬运的动力来源分析,指出风力作用是形成本区地下水水化学异常的控制因素,化学组分源于柴达木盆地西北部含盐地层及盐湖盐类晶粒。
The Golmud alluvial fan groundwater is rich in strontium, and the groundwater hydrochemistry zone is different from the normal alluvial fan groundwater hydrochemistry zonal law. Through indoor water-rock simulation tests and field monitoring, it is proved that the material of groundwater and mountain sediments is not the product of in-situ weathering of bedrock. Based on the analysis of the source of regional geochemical background and material handling, it is pointed out that the wind action is the controlling factor for the formation of hydrochemical anomalies in groundwater in this area. The chemical components originate from the salty strata in the northwestern part of the Qaidam basin and the salt crystals in the salt lake.
