山东省东平县大高庄铁矿床地质特征及矿床成因

摘要

Dagaozhuang iron deposit belongs to "Anshan type" sedimentary metamorphic iron deposit. Its ore bodies are hidden in the depth of 40~48m in the underground. It occurred in ShancaoYu formation of Taishan group. Its lithology is magnet quartzite. The deposit is composed of three ore belts and 9 ore bodies. Among them,Ⅰ 1 ore body is the main ore body;The average grade of TFe is 30.09% and mFe is 22.51%. Its industrial ore type is weak magnetic lean ore. Through analysis and study on geological characteristics and origin of Dagaozhuang gold deposit, it will provide effective and reasonable exploration method and means for searching the same type of i⁃ron deposit.%大高庄铁矿属“鞍山式”沉积变质型铁矿床，矿体隐伏于地下40～48 m，赋存于泰山岩群山草峪组地层中，岩性为磁铁角闪石英岩，矿床由3个矿带9个矿体组成，其中Ⅰ1为主矿体，矿床平均品位 TFe 30．09％， mFe 22．51％。矿石工业类型为需选弱磁性贫铁矿石。通过对大高庄铁矿地质特征及矿床成因进行分析研究，对今后寻找同类型铁矿以及选择有效合理的勘探方法和手段具有重要意义。
