| 摘 要： | 筏子坝铜矿矿体与围岩磁性差异显著,各矿体均有明显的磁异常反映,说明地面高精度磁法测量是寻找碧口群中火山岩型铜矿的一种有效手段。通过对磁异常特征分析研究,建立了该区火山岩型铜矿的地质—地球物理综合找矿模型。提出了碧口—阳坝铜矿带火山岩型铜普查应按综合研究圈定成矿远景区,地质测量和地面高精度磁法测量、异常检查验证三步进行的工作建议。

| Abstract: | Applying high-accuracy ground magnetic survey to Faziba copper deposit,it isfound that the orebodies differ greatly with their country rocks in magnetic property,and eachorebody is of distinct anomaly show.By studying and analysing the features of the magneticanomalies,a comprehensive geological-geophysical prospecting model related to igneous rock-type copper deposit of the studied area is established.It is suggested that,for the igneous rock-type copper reconnaissance of Bikou-Yangba copper deposit zone,following steps should be car-ried out:first,outlining prospective metallogenic area,then geological survey, high- accuracyground magnetic survey and anomaly check and verification. |
