摘　　要：抚顺地区金矿氧化带中金的次生富集特征十分明显,可划分为氧化淋滤贫化带、次生富集带、原生带三个带。次生富集带中金的富集原因主要为原生金矿中的金矿物在氧化环境下溶解或形成胶体金,迁移至有利于汇集的还原环境时发生沉淀并富集。Au deposits in Fushun,Liaoning are characterized by strong secondary enrichment.The deposits may be divided into leached zone,secondary enrichment zone and primary ore zone.Au in the leached zone was dissolved,forming colloidal gold which transported into reduced environment and deposited,forming enrichment.
