青海拉水峡铜镍矿床综合找矿模型及找矿预测

Prospecting and Prediction Model for Lashuixia Copper-Nickel Deposit in Qinghai

在拉水峡铜镍矿区开展地质-地球物理勘探-地球电化学综合勘查方法找矿的基础上,通过对已知矿体的地质、地球电化学信息和低阻、高磁的地球物理找矿异常特征的研究,建立了拉水峡铜镍矿床地质-地球物理勘探-地球电化学勘查综合找矿模型:以矿体的地质信息为基础,地球电化学异常、高精度磁异常及TEM异常的组合。利用综合找矿模型,进行了隐伏矿体的勘查和综合找矿预测,在矿区发现了4个地球电化学镍、铜的异常带,其中3个属于浅隐伏靶区,1个为深隐伏靶区。

The geology-geophysical geoelectrochemical prospecting of Lashuixia is established based on geology geophysical geoelectrochemical exploration method and the information of geoelectrochemical method and geophysics anomalies in copper-nickel deposit in Lashuixia. The model includes the geology information of ore body, the abnormity of geoelectrochemical method, the scheme of geophysical prospecting abnormity. The bur- ied ore deposits are forecasted by compositive prospecting model in Lashuixia area. Four Cu-Ni anomaly zones of geoelectrochemical are found. There are three low buried ore target areas and one deep buried ore target area among the anomaly zones.
