宁夏广武山铜矿特征及成矿规律

Copper characteristics and metallogenic regularity in Guangwu Mt.,Ningxia

从宁夏广武山铜矿矿化特征分析成矿原因,试图找出成矿规律.在已有资料的基础上,研究了该地区含矿地层区域铜矿化特征.结果表明,该地区原生黄铜矿型铜矿的原生沉积和次生富集的发生与褪色带关系密切,形成似层状矿体.退色带中铜矿化是氧化-还原过渡带环境的产物,是成矿的有利部位.广武山地区寻找铜矿应注意研究相对应的有利地质成矿部位,可望有新的发现和突破.

The metallogenic causes of copper ore in Ningxia Guangwu,were analysis to find metallogenic regularity.Mineralization features of copper ore were researched in the region of ore-bearing strata on the base of existing data.The results show that there are closely relations between deposition of primary chalcopyrite-type native copper to the occurrence and fading of secondary enrichment zone in the area,and then,layer-like ore body was formed.Mineralization of copper was result of environment of oxidation-reduction transition zone,which was in fading zone,the favorable ore-forming parts.It is worth noting that the corresponding parts of the favorable geological ore are expected to have new discoveries and breakthroughs in search of copper ore in Guangwu Mt.
