摘　　要：中条山地区主要经历了四次与铜、金有关的重大地质事件,分别是新太古代花岗岩一绿岩带、古元古代裂谷作用、中元古代火山活动和中生代岩浆作用,其中以前二次最为重要。中条山北、东段以古元古代裂谷作用为主,叠加了中元古代火山作用和强度较弱的中生代岩浆活动,成矿以铜为主,其次为金。西南段以新太古代花岗岩-绿岩带的地质事件为主,并叠加较为发育的中生代岩浆活动,成矿以金为主,其次为铜。本区是铜、金成矿条件十分有利地区,有较好的找矿前景。Zhongtiao Mts. area underwent Neoarchean granitoid-greenstone belts forming,Paleoproterozoic rifting,Mesoproterozoic volcanism and Mesozoic magmatism totally four-times important events, which have relation with copper and gold mineralization.The first two of them are more important. In the north and the east parts, Paleoproterozoic rifting developed well,and then Mesoproterozoic volcanism and weak magmatism overprinted on it. In the southwest part, Neoarchean granitoid-greenstone belts forming is the most important geological event, and the strong Mesozoic magmatism overprinted on it, the mineralization is mainly gold and secondly copper. This area is very importamt region for prospecting copper and gold ores.
