浅析硅化蚀变带在河西金矿成矿过程中的作用

Role of Silicified Alteration Belt in Ore Forming Process of Hexi Gold Deposit

通过对河西金矿硅化蚀变带及矿化富集规律的研究,认为硅化蚀变带类似断裂蚀变带,在含矿热液运移过程中起导矿和容矿作用,既可以为矿液运移提供通道,又能为富集成矿提供场所。并讨论了硅化蚀变与矿化富集规律在找矿方面的指导意义。

It is held through the study of the silicified alteration belt and law of mineralization enrichment that the silicified alteration is similar to a fracture alteration belt,which plays a role of ore-guiding and ore-hosting in the movement of ore-forming solutions.It can provide the channel for ore solution and also the site for ore formation.The guidance significance of silicified alteration and mineralization enrichment to ore prospecting is also discussed.
