摘　　要：红石地区处于河南围山城金银成矿带的东延部位 ,成矿条件十分有利。碱性岩、斜长角闪岩、基性 -超基性岩与金银成矿密切相关。环放状断裂体系、北东向断裂、南北向断裂以及断裂交汇区是金银矿的有利控矿构造。北东向断裂中易成金 ,南北向断裂中易成银。成矿地质条件表明 ,擂鼓台一带具有良好的找矿前景。Situated in the east part of Henan Weishancheng Au Ag metallogenetic belt, the Hongshi area is very favorable for Au Ag mineralization which shows close relationships with Alkalic intrusions, amphibolite and mafic ultramafic rocks. Favorable ore controlling structures including ring radial faults, NE tracked faults and their intersecting part. Gold bearing bodies often situate along the NE striking faults, and silver ore bodies regularly in SN striking faults. Analyses of ore forming geological conditions show that the Leigutai area in Hongshi is an excellent belt for prospecting.
