摘　　要：鄂西马滑沟金矿为受韧 -脆性剪切带控制的中低温岩浆热液型矿床 ,矿体剖面具有矿化分带性、似等距性、透镜体自相似性等特点。据此对以 Au- 9异常区为代表的第三矿化中段 ( C中段 )进行了找矿预测 ,这对马滑沟金矿及相关类型金矿床取得找矿突破有其现实意义。Mahuagou gold ore deposit is a mesothermal epithermal one controlled by ductile brittle shear zone.It is characterized spatially by zoning,equidistant distribution and selfsimilarity of the mineralization across the zone,and temporally by pulsation and succession.A search for the most likely location has been carried out on the Au 9 anomalous geochemical area in the third level(C level)based on the above metallogenetic regularity.It may serve as a guide for the prediction of gold of the shear zone type and related types in Mahuagou and other areas.

关 键 词：剪切带型金矿 矿体赋存 找矿预测
