摘　　要：隐伏矿床定位预测理论和技术是国际矿床学界研究的热点和难点。结合20多年的科研找矿实践,针对隐伏金多金属矿床的找矿难题,提出必须走地质、地球物理与地球化学相结合的道路,将有利的成矿构造部位(储矿构造或含矿构造岩相带)作为定位预测的目标,全面认识和解释地质与地球物理的关系。阐述了"地物化三场异常耦合"定位预测理论的3个基本原则,即预测目标、预测尺度和预测精度。介绍了成矿地质结构场、成矿地球化学场和成矿地球物理场的基本含义和要点,推荐了经过实践检验的、有效的地质、地球物理、地球化学技术方法组合,并通过3个实例说明应用该理论和方法的工作流程与实际效果。The studies of theories and technologies for positioning prognosis of concealed ore deposits are hot points and difficulties of international mining science communities.In combination with the experiences of scientific prospecting for concealed ore deposits over 20 years,and aiming at the difficulties of prospecting for concealed gold-polymetallic deposits,it is proposed that there must be a combination of geology,geophysics and geochemistry,the favorable metallogenic structural sites(ore-housing structures or ore-bearing tectonolithological facies zones)should be the targets of positioning prognosis,the relationship between geology and geophysics should be understood and interpretated comprehensively.The three basic principles of the“geological-geophysical-geochemical three field anomalies coupling theory”,i.e.predicting target,scale and accuracy,are expounded.The basic meaning and main points of metallogenic geological structural filed,geochemical field and geophysical field are introduced.The integrated geological-geophysical-geochemical technological combinations which have been proven effectively are recommended.In the end,three instances are displayed to present the workflow and practical effect of applying the theory and technologies.
