高山植被覆盖区大型铜矿快速勘查模式——以哀牢山南段云南金平金竹冲矿区为例
|
摘要
云南省金平县金竹冲铜矿区地处扬子板块与青藏滇板块缝合线上,属哀牢山变质地体的南端东缘,该区为哀牢山地体边缘地壳增生带,主要由深变质岩系组成。工作区内地形起伏较大,为高山植被覆盖区,找矿难度大。本文以该矿区为例,综合应用高精度磁法、双频激电法和EH4测量三种地球物理方法进行找矿勘探,辅以土壤化探方法对地球物理异常进行约束,结合地质资料进行解译,预测了有利的成矿区域,并进行有效的工程勘探验证,推测该矿区具巨大的成矿潜力,初步建立了高山植被覆盖区铜矿的快速勘查模式。
Jinzhuchong copper deposit in Jinping county of Yunnan province is on the suture zone between the Qinghai—Xizang(Tibet)—Yunnan plate and Yangtze plate, which belongs to the southeast section of the Ailao Mountains metamorphic terrane. The area is among the crust accretionary belts of the Ailao Mountains metamorphic terrane which is chiefly composed of high-grade metamorphic rocks. The deposit is located in a vegetable-covered high mountain area with big topographic relief, where exploration is a difficult problem. This paper takes this deposit as an example and comprehensively applies high-precision magnetic survey,dual-frequency IP and EH4 to do prospecting work. The geophysical was worked out according to soil geochemical exploration and geological information. In this way the paper has predicted favorable mineralization targets and then done effective engineering test. The result shows that the deposit has vast metallogenic potential, and the fast prospecting model in vegetable-covered high mountains was initially established in southern section of the Ailao Mountains.
