地质界面成矿现象普遍存在,从成矿作用的角度看,控矿地质界面可分为3类:成矿地质条件变化界面;成矿要素性质演化界面;矿体形成界面.地质界面的控矿原理在于:界面两侧异相差异因素为成矿提供了动力;界面附近构建的特殊过渡态为成矿提供了特定的环境;界面对应的成矿时间是最佳成矿期;界面物理化学效应促进了成矿作用的进行.运用地质界面控矿原理进行找矿预测,关键是准确识别并定位地质界面,研究其性质并理解其控矿作用,并融合其他成矿理论进行综合分析,同时注意地质界面控矿在地质异常解释中的运用.

The phenomenon of interface-metallogenesis is universal. From the perspective of metallogene-sis, geological interface can be divided into ore-forming environment-changing interface, ore-forming element's nature-evolution interface and orebody-forming interface. The interface control of the the ore-forming can be effective mainly because of the metallogenic dynamics produced by the difference between the phases of opposite sides of the interface, the special metallogenic environment offered by the transitional state around the interface produces, the best metallogenic epoch and the accelaration of the metallogene-sis by the effect of physics & chemistry. In the application of interfacial-metallogenesis in ore-prospecting and prediction,the key is to distinguish and locate the geological interface,study its nature and ore-controlling mechanism. Meanwhile, the study should be blended with other metallogenic theories and comprehensive analysis,in order to apply the interface-metallogenesis to explain the geological anomaly.
