安康地区采集地表溪水作为铀矿水化学找矿可行性研究

Feasibility study on collecting surface water from Ankang area as uranium ore chemical prospecting

通过分析陕西安康(幅)试验区水文地质条件,针对在铀水化学找矿中的地下水和地表水溪水采样工作,重点论述地表溪水铀水文地球化学找矿效果,从地表溪水中铀的区域分布特点、变化规律、异常展布特征及其成因、找矿效果和经济实效等方面与地下水进行对比,认为:采集地表溪水水化学找矿具有简捷,快速,劳动强度低的优点,在秦岭及其以南水文网发育地区的铀矿水化学区调扫面,也可用采集地表溪水可以代替地下水。最终肯定了地表溪水找矿的可行性和效果,为今后其它类似地区采用地表水代替地下水进行铀水化学区找矿提供了参考依据。

By analyzing the hydrogeological conditions of the Ankang (Amplitude)test area in Shaanxi Province,focusing on the sampling of groundwater and surface water streams in uranium water chemical prospecting,the uranium hydrogeochemical prospecting effect of surface irrigated water is discussed.The characteristics of regional distribution,variation law,abnor- mal distribution characteristics and its genesis,ore -seeking effect and economic efficiency are compared with groundwater.It is considered that the collection of surface water and water chemical prospecting has the advantages of simplicity,rapidity and low labor intensity in Qinling.The surface of the uranium ore water chemical zone in the development area of the South Hydrographic Network can also be used to replace groundwater.Finally,it affirmed the feasibility and effect of surface shale water prospecting,and provided reference for future uranium water chemical area prospecting by using surface water instead of groundwater in other similar areas.
