河南省南召县乔端地区铜矿床地质特征及矿床成因

南召县乔端地区铜矿成矿地质条件较好。该地区铜矿床多分布于火神庙组酸性火山岩石英角斑凝灰岩中，受断裂控制不明显，围岩具显著的热液蚀变，属火山热液沉积型块状硫化物铜矿床。本文在研究南召乔端地区多个铜矿床的第一手翔实地质勘查成果资料的基础上，总结了乔端地区铜矿床地质特征及找矿标志，并对矿床成因进行了讨论，以期对乔端地区及外围寻找铜矿床提供参考。

Geological characteristics and genesis of the copper deposit in Qiaoduan area, Nanzhao County, Henan Province

Ore-forming geological conditions of the Qiaodan copper deposit in Nanzhao County are good. The copper deposits are mainly distributed in the quartz corner porphyry tuff of the acid volcanic rocks of the Huoshenmiao formation, and are not obviously controlled by faults. On the basis of the first-hand detailed geological exploration data of several copper deposits in Qiaoduan area, Nanzhao County Province, this paper summarizes the geological characteristics and prospecting criteria of the copper deposits in Qiaoduan area, Nanzhao County, and discusses the genesis of the deposits, it is expected to provide a reference for the exploration of copper deposits in Qiaoduan area and its periphery, Nanzhao County, Henan Province.
