摘要:
耳泽金矿床位于特提斯成矿域的甘孜一理塘成矿带，该成矿带为重要的贵金属成矿区，具有较好的找矿前景。矿区及外围大量的岗达概组碳酸盐岩为矿床形成提供了丰富的物质来源，多期构造活动导致北西向断裂和耳泽背斜在矿区交会，耳泽背斜核部及发育的次生构造破碎带、节理裂隙带、大理岩中溶洞为矿物质运移、富集和沉淀提供了良好的地质条件，成矿地质背景十分优越。目前，矿区已圈定12个矿体，金资源量规模|已达中型。耳泽金矿床与红土坡金矿床对比，二者在区域构造、地层岩性、成矿部位及成矿机制具有高度的相似性，如加强科研和勘查投入，在二者之间及其附近的空白区域有望取得重大找矿突破。

Abstract:
The Erze Gold Deposit is located in the Garze-Litang metallogenic belt within the Tethys metallogenic domain, an important precious metal metallogenic zone with promising prospecting potential. The extensive Gangdagai Formation carbonate rocks in the mining area and its periphery provide a rich material source for the deposit. Multi-phase tectonic activities resulted in the intersection of NW-trending faults and the Erze anticline in the mining area. The core of the Erze anticline, along with secondary structural fracture zones, joint-fissure zones, and karst caves in marble, created favorable geological conditions for mineral migration, enrichment, and precipitation, indicating a highly advantageous metallogenic geological setting. ' To date,12 orebodies have been delineated in the area, and the gold resource has reached a medium-scale deposit size. A comparison of the Erze and Hongtupo gold deposits reveals significant similarities in regional structure, stratigraphie lithology, ore-forming positions, and metallogenic mechanisms. Enhanced research and exploration investment in the blank areas between and in the vicinity of both deposits could lead to major prospecting breakthroughs.
