摘　　要：金英金矿位于浑江盆地与龙岗隆起的交汇处,成因类型为浅成低温热液型.中太古界三道沟岩组、古元古界珍珠门组、新元古界钓鱼台组是找矿的地层标志,北东向盆缘断裂F101、珍珠门组与钓鱼台组的层间滑动破碎带F100是构造标志,晚侏罗世花岗斑岩为岩浆岩标志.在此基础上提取出14个预测要素,根据每个预测要素的权重赋予不同数值从而建立起预测模型.通过马鞍岗等金英金矿区外围找矿实践验证,该预测模型对寻找金英式金矿具有一定指导意义.The Jinying gold deposit is located in the junction of Hunjiang basin and Longgang uplift, genetically belonging to epithermal type. The stratigraphic criteria for prospecting include Mesoarehean Sandaogou formation, Paleoproterozoic Zhenzhumen formation and Neoproterozoic Diaoyutai formation. The tectonic indicators are the NE-trending basin marginal fault F101 and the interlayer-gliding fractural zone F100 between Zhenzhumen and Diaoyutai formations. The magmatic clue is the Late Jurassic granite porphyry. Based on these criteria, 14 prediction factors are extracted to establish the prediction model according to the prediction factors with assigned values for different weights. With prospecting practice in the periphery of Jinying gold orefield such as Ma＇angang, the model is verified of its guiding significance for searching the Jinying-style of gold deposits.
