斑岩铜矿是许多国家的主要铜矿矿床类型,我国也在积极开展这一矿床的普查找矿工作.自1960至1972年12年中,国外发现40个大中型斑岩铜(钼)矿床,第三世界占22个.化探在找斑岩铜矿中作出了重大贡献,因此普遍认为化探方法是找斑岩铜矿的一种基本手段.一、条件有利斑岩铜矿显著特点是比其他热液矿床规模大;埋藏较浅,常有铁帽或近地表的次生富集带出现,容矿岩体或围岩发生强烈破裂作用,裂隙发育,有利于水和氧的渗透及风化产物的
Porphyry copper deposits are the main types of copper deposits in many countries and our country is actively carrying out census and prospecting work for this deposit.40 large and medium-sized porphyry copper (molybdenum) deposits were discovered abroad during the 12 years from 1960 to 1972 , The third world accounted for 22. Geochemical exploration in finding porphyry copper made a significant contribution, it is generally believed that the geochemical exploration method is to find a basic means of porphyry copper deposits. First, the favorable conditions of porphyry copper significant features Is larger than other hydrothermal deposits; shallow burial, often with cap or near surface secondary enrichment zone appears, the ore-bearing rock mass or wall rock strong rupture, fracture development, is conducive to water and oxygen infiltration And weathered products
