Abstract:

Qibozi Gold-Silver Polymetallic Deposit is a newly discovered magmatic hydrothermal fluid deposit in Eastern Hebei high ore concentration area.10 ore bodies in the district have been discovered.The ore bodies occur in the interlayer fragmentation zone and fractures,displaying the characteristics of branching and reuniting,pinching out and reappearance.All of them are fractured altered rock type.Gaoyuzhuang Formation,NE(NEE) and EW faults and Yanshanian magmatic rocks evidently control the mineralization in the district and are important ore-controlling factors.The third and fourth member of Gaoyuzhuang Formation,NE and EW faults and their turnings,Yanshanian intrusion rock,silicification,sericitization,skarnization,pyritization and so on are important prospecting indicators in the area;Ag,Au,As,Mo,Mn element anomalies,low resistance and high polarization anomalies and so on are important geochemical and geophysical prospecting indicators in the area.
