| 摘 要： | 铜在自然界中多以氧化物和硫化物形式存在,只有少部分以单质或者合金状态产出。总结了自然铜矿化的类型、特点、形成条件以及成矿机理,阐述了找矿前景。自然铜的矿化类型主要有岩浆岩型、砂岩型等,部分与有机质共生或产在氧化带,产出环境为低温、弱碱性还原环境。玄武岩型自然铜矿化分布广、规模大,是形成工业矿床最有利的矿床类型;砂岩型自然铜矿床主要见于湖南麻阳一带,成矿前景优越,有可能找到更多更大的工业矿床(体)。

| Abstract: | Sulfide and oxide are the familiar minerals of copper,and native copper is peculiar in nature.We summarized the types and characteristics of native copper deposits,and discussed the ore-forming mechanisms,then estimated the possible prospecting area.Native copper was formed in lower temperature and feebleness redox conditions,hosted by flood basalts,sandstone,intermediate-acid magmatic rocks or oxidation zone,and some occur with organic matter.Native copper deposits,associated with basalts are widely distributed in northwest or southwest China,many have economic value.Sandstone-hosted native copper deposits also show a good prospecting perspective in Mayang of Hunan Province. |
