摘　　要：莱芜接触交代-热液铁矿赋存于奥陶系马家沟组碳酸盐岩与燕山晚期闪长岩的接触带及其附近。通过对各矿床有益有害组分分析,以及对成矿母岩、围岩岩石化学特征、双交代渗滤作用和围岩蚀变类型等研究,总结出“三位一体”成矿模式,进而探讨了矿体的空间分布规律及其找矿意义。Laiwu hydrothermal metasomatic iron deposit is located at contact zone of Ordovician carbonate rock （Maiiagou Formation） and Late Yanshanian diorite or nearby. Study on the analysis of ore elements, gangue elements or rock, bi-lateral replacement poisonous elements, petrochemic and wall rock alterations leads to al characteristics of the wall rock and host the metallogenic model of three in one which reveals the ore spatial distribution regularity thus is significant to further ore exploration.

关 键 词：莱芜铁矿 接触交代 渗滤 “三位一体”成矿模式 山东省
