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.
