摘要

莱芜式接触交代-热液铁矿赋存于奥陶系马家沟组碳酸盐类岩石与燕山晚期闪长岩的接触带及其附近。通过研究柴庄矿区地质特征及岩体分布特征,推测出矿体受辉石闪长岩和竹叶状砾状灰岩接触带控制,据南侧矿坑一壁所见辉石闪长岩和灰岩接触界线产状,推测矽卡岩铁矿体倾向南西,倾角75°,属于莱芜式接触交代-热液铁矿。
        Laiwu type contact metasomatic-hydrothermal iron ores occur in contact zone of Ordovician carbonate rock(Majiagou Formation)and late Yanshanian diorite or its nearby area.By studying geological features and orebody distribution characteristics of Chaizhuang mine,it's inferred that the orebody is controlled by contact zone of diorite and wormkalk.By looking at one wall of south pit for occurrence state of contact line of pyroxene diorite and limestone,it's inferred that skarn iron orebody dips southwest,with an angle of 75°and it belongs to Laiwu type contact metasomatic-hydrothermal iron ore.
