摘　　要：降低勘查风险、实现科学找矿一直是国内外矿产勘查界不断探索的前缘领域和研究热点,而勘查区找矿预测理论与方法是解决这一难题的有效途径。该方法将成矿作用内因(元素的地球化学特征)和外因(地质作用类型)相结合,构建以成矿地质体、成矿构造与成矿结构面和成矿作用特征标志为主要内容的找矿预测地质模型,通过大比例尺构造蚀变填图、物化探测量和专题研究等综合方法,预测推断矿体赋存位置,最后通过工程施工,发现并查明工业矿体(矿床)。依据勘查区找矿预测理论与方法,在四川拉拉铜矿、新疆玛尔坎苏锰矿带穆呼-玛尔坎土锰矿及内蒙古大兴安岭南段敖脑达坝地区锡多金属矿开展找矿预测,取得了较好效果。Reducing exploration risks and realizing scientific prospecting always have been frontier fields and research hotspots in the world of mineral exploration,the theory and method of ore prospecting prediction for exploration area is the valid channel to deal with this problem.Using this method,a geological model of ore prospecting can be established by combining the internal(geochemical behavior of elements)and external(types of geological processes)control factors for mineralization.The main components of the prospecting prediction model include geological bodies related to mineralization,metallogenetic structure planes and mineralization characteristics.Together with the results of special geological mapping,geophysical and geochemical exploration on large scale,orebodies have been located by synthetic information and explored by drilling.Case studies of the Lala copper deposit in Sichuan,Muhu-Maerkantu manganese ore deposit in Xinjiang and Aonaodaba tin-polymetallic deposit in Inner Mongolia,illustrate the effective application of this method in ore prospecting prediction.
