| 摘 要： | 三维地质建模是当前国内外矿产资源勘查与评价研究的重要途径和热点.以栾川钼多金属矿区为例，针对研究区地质背景复杂、成矿地质条件多样性特征，开展了基于地质(岩性地层及其物性特征、地质体产状数据)与重磁正反演集成技术组合的三维地质模型建模研究，其研究内容为:(1)根据研究区地质背景和成矿条件，确定研究区矿床地质特征以及近地表地质体的空间属性特征；(2)利用重磁数据，在定性解译地质信息的基础上，开展二度半正演方法定量解译研究，并运用三维位场概率成像方法反演和解译深部地质体；(3)根据研究区地质与重磁反演解译资料综合分析，确定晚侏罗世斑岩岩体和控矿构造的时-空-因关系.研究结果表明，基于地质岩性属性特征的重磁正反演联合解译，能够综合利用地质体之间的物性差异、成因关系界定其几何形态，从而在三维环境中建立它们的时空关系，即三维地质模型，为研究区深部找矿、矿体定位预测以及金属矿产资源定量评价提供技术支撑和新途径
