青海省拉水峡铜镍矿床物化探找矿研究及成矿预测

The Study of prospecting with geophysical and geochemical exploring methods and metallogenic prediction in qinghai lashuixia Cu-Ni deposit

以矿区地质背景及成矿环境为基础,用地球电化学信息和低阻、高磁的地球物理异常等信息,结合地球电化学勘查与地球物理勘探方法建立了拉水峡铜镍矿床综合找矿模型,并利用找矿模型对拉水峡矿区的隐伏矿体进行了预测,在找矿预测中发现了四处具有找矿前景的多种方法组合异常。

Lashuixia ore deposit is one of the most important Cu-Ni deposits in Qinghai Province.It has particular geological background and mining environment of.Based on the study of the electro-geochemical,low resistant and high magnetic nomalies featurea,the authors conclude a comprehensive exploring model combining with the geophysical and electro-geochemical exploring methods,and prospect concealed ore using the model in this mining.Finelly,four abnormal targets were found in external and deepper areas of the deposits by geo-electrochimestry methods,which provides the evidence for further surveying and geological work.
