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地质特征及含矿性,及矿体的规模、形态、产状及赋存规律、矿石类型和结构构造等特征,总结了金矿赋存特征,及矿床成因,同时指出了本区的探矿方向,扩大向深部和外围空间的找矿,本区具有构成大型金矿的资源潜力,对延长矿山年限有积极意义。文章在分析了矿床的地质特征的基础上得出三合金矿为中低温热液蚀变-表生富集型金矿床。
Sanhe gold mine is located in Luanchuan county in Henan province,and the main ore body is produced in northwest–southeast structural mineralized zone.Through controlling the prospecting work of the earth surface and gallery,this paper generally finds out the geological characteristics and ore-bearing potential of middle-to-shallow mineralized alteration zone and the scale,form,occurrence and characteristics of the ore body,including existence law,ore types,structures,etc.,summarizes the existence characteristics and deposit metallogenesis of the gold ore,and indicates the prospecting direction of this area at the same time to expand the prospecting work to the deep and peripheral space.This area has the resource potential to form a large-scale gold ore and has positive significance for extending the life of mine.Based on analyzing the geological characteristics of deposit,this paper concludes that Sanhe gold ore belongs to a mesothermal-to-hypothermal hydrothermal alteration-supergene enrichment gold deposit.
