摘要:
胶西北金矿集区作为中国最重要的金矿集区之一，其金资源不仅集中且成矿过程复杂。红布金矿床为胶西北金矿集区内的典型金矿床。近年来，随着生产开采，浅部矿体逐渐枯竭，亟须通过成矿理论创新和勘查技术进步来延长矿山服务年限。通过融合多源地质数据，采用隐式建模方法，建立红布金矿床三维地质模型。基于该三维模型，通过概念建模、数值建模、模拟设计等，对成矿过程进行了数值模拟，结果表明，红布金矿床西北部外围深边部存在一定成矿潜力，单期成矿作用持续时间不超过 2 500 a，可为成矿时间尺度提供约束。该成果可有效降低勘探成本，明确下一步找矿勘探方向，可为同类矿床寻找接替资源提供借鉴。

Abstract:
As one of the most important gold provinces in China, the Northwest Jiaodong gold province is charac⁃terized by highly concentrated gold resources and complex metallogenic processes. The Hongbu Gold Deposit is a typicalrepresentative within this area. In recent years, with continuous mining activities, shallow orebodies have graduallybecome depleted, creating an urgent need to extend the mine’s service life through innovations in metallogenic theoryand advancements in exploration technology. By integrating multi⁃source geological data and applying implicit modelingtechniques, a 3D geological model of the Hongbu Gold Deposit was established. Based on this model, the ore⁃formingprocess was numerically simulated through conceptual modeling, numerical modeling, and simulation design. Theresults suggest that the deep part and peripherals in the northwest of the Hongbu Gold Deposit show certain metallogenicpotential. The duration of a single mineralization event does not exceed 2 500 a, which provides constraints on themetallogenic timescale. This research can effectively reduce exploration costs, clarify future exploration directions, andoffer guidance for identifying substitute resources in similar deposits.
