摘要
秦岭造山带中柞-山盆地铜矿点众多,主要铜矿类型为斑岩型、热水喷流-改造型,结合近期勘查成果和综合研究进展,认为这些矿点可能同属于岩浆-热液-沉积成矿系列。本文在总结区内铜矿床地质特点的基础上,以区内主要铜矿勘查实例为依据,综合地、物、化找矿信息,提出有效的找矿方法为高精度磁法扫面、大地测深定位,地质钻探验证,为区内寻找铜矿提供了新的勘查思路与方法。
There have a great number of copper ore occurrences in Zha-Shan basin of Qinling orogenic belt, most of which belong to porphyry type, hydrothermal exhalative type, and reformed type. It is concluded that these ore occurrence may attribute to magma-hydrothermal-sedimentary metallogenie series combined with late prospecting result and comprehensive research advance. On the basis of analyzing geological features of copper deposits and judging by principal copper deposits exploration examples, integrating geological, geophysical, and geochemic prospecting information, it is proposed that effective exploration methods are high precision magnetic measurement, magnetotelluric sounding locating, and drill confirmation, which provided new prospecting thoughts and methods for exploring copper ore deposit in the Zha-Shan region.
