河南省赵家沟铜矿地质特征及矿床成因探讨

Geological Characteristics and Genesis of Zhaojiagou Copper Deposit in Henan Province

赵家沟铜矿处于华北陆块南缘,矿体产于太古界雪花沟组中段的含石墨黑云二长片麻岩中,受区内断裂构造控制,区内成矿作用主要表现为构造-流体成矿,成矿方式以充填交代作用为主。通过研究分析矿区地质特征及物探异常,认为矿床成因为热液充填-交代型铜矿床,总结了本区铜矿的找矿标志,旨在为指导本地区同类型矿床的勘查提供借鉴。

Zhaojiagou copper deposit is located in the southern margin of the North China continental block.The ore body occurs in the graphite bearing biotite monzonite gneiss in the middle of the xuehuagou formation of the Archaean.Controlled by the fault structure in the area,the mineralization in the area is mainly structural fluid mineralization,and the mineralization mode is mainly filling metasomatism.Based on the study and analysis of the geological characteristics and geophysical anomalies of the mining area,this paper considers that the deposit is due to the hydrothermal filling metasomatic copper deposit,and summarizes the prospecting criteria for finding copper deposits in this area,in order to provide reference for guiding the exploration of similar types of deposits in this area.
