摘　　要：成矿预测的目的就是利用综合的有利的成矿地质条件对具有找矿前景的区域进行圈定预测。马超营深大断裂东段的成矿预测主要采取地质类比法、矿床模式研究及深大断裂东西两段的对比法。成矿标志是综合成矿地质条件的选择。如断裂构造是构造蚀变岩型金矿的主要标志,花岗斑岩岩株是斑岩型钼矿的主要标志,燕山期花岗岩基金是钼铅锌矿床共同的预测标志。地球化学异常标志是所有多金属矿床的成矿预测的首选。不同的矿种具有不同的成矿预测标准,明显高于背景异常者即可进行成矿预测圈定。The purpose of mineralization prediction is to delineate and predict regions with ore-prospecting prospects by using comprehensive favorable ore-forming geological conditions.The metallogenic prediction of the eastern part of the Macaoying deep and large fault mainly adopts the geological analogy method.The study on ore deposit model and the comparison method between east and west sections of deep and large faults.The mark of mineralization is the choice of comprehensive metallogenic geological conditions.For example:fracture structure is the main symbol of tectonic eroded rock gold mine;granite porphyry strains are the main symbol of the porphyry-type molybdenum ore;Yanshan Granite Fund is the common prediction mark of molybdenum lead-zinc deposits.;geochemical anomaly mark is preferred for mineralization prediction for all polymetallic deposits.Different ore species have different ore prediction criteria,mineralization prediction can be performed with significantly higher background abnormalities.
