摘　　要：三合金矿位于河南省栾川县境内,主要矿体产于NW-SE向构造矿化带内,通过地表及坑道探矿工程的控制,大致查明了中浅部矿化蚀变带的地质特征、含矿性和矿体的规模、形态、产状,矿石类型和结构构造等特征,总结了矿床成因及金矿体的赋存规律,同时进一步指出了本区的探矿方向,即扩大向深部和外围空间的找矿,结果表明本区具有形成大型金矿的资源潜力,对延长矿山年限具有重要意义。Sanhe gold deposit which is located at the Luanchuan, Henan province, is found in the NW - SW oriented structure mineralized zone. The geological and mineralizing characteristics of mid - superficial alteration zone, and scale, shape, occurrence, ore texture and structure of ore - body is investigated in the exploration engineering on the surface or in the sap. The metallogeny and regularity of this deposit is summarized based on the above observation, and the future exploration direction is the deep and periphery of this deposit which is the most favorable prospection target. The analysis tell that this deposit maybe enlarged to be a large - scale gold deposit which is meaningful for prolong serve age of this deposit.
