宁夏西华山地区簸箕掌铜金矿床地质特征及成矿地质条件分析
Geological characteristics and metallogenic conditions of Bojizhang copper-gold deposits in Xihuashan area,Ningxia Hui Autonomous Region
摘要
Abstract
Xihuashan area is one of the crucial prospects of Au polymetallic deposits in Ningxia Hui Au-tonomous Region.The Bojizhang Cu-Au deposit is the largest deposit discovered in this area.Based on the previous data and results this article summarizes up detaily the geological characteristics and analyze the ore-forming condition of the deposit.The main ore bodies are mainly composed of Au,Cu-bearing graphitized mica quartz schist,albite dike and Cu-bearing fractured quartz veins,generally controlled by structure and distributed along the joints,tectonic fractures and quartz veins.The ore-hosting surround-ing rock includes graphitic mica quartz schist,graphitic marble and albite-quartz-mica schist.The ore is characterirized by massive and disseminated structure and dominated by oxidized ore.The surrounding rock alteration is weak,including mainly limonitization and pyritization.Cu-Au mineralization in Xihuas-han area is controlled by metamorphism of the strata,tectonic movement and magmatic activity.The Cu-Au mineralization are controlled by strata metamorphism,tectonic activity and magmatic activity and ge-netically the deposipts belong to sedimentary-metamorphic-hydrothermally reworked Cu-Au deposit.关键词
