摘要: 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。

Abstract: 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.

Key words: Silicified alteration, Wall rock alteration, Fracture alteration belt
