摘要
沟西—西官庄铁矿床位于苍山县沟西铁矿区,鲁西隆起区南缘尼山—白彦断块凸起与陶枣断陷盆地之间,新太古代泰山岩群山草峪组地层中,为全隐伏矿床。岩性主要为黑云变粒岩,局部夹磁铁石英角闪岩、磁铁角闪石英岩、黑云角闪片岩等。矿石为低品位的贫铁矿,是典型的沉积变质型(鞍山式)铁矿。通过对苍山县沟西—西官庄铁矿区成矿地质背景及矿床地质特征、矿石特征等进行分析,总结其成矿规律,对进一步寻找沉积变质铁矿有一定的指导意义。
Ditch West-West Guanzhuang iron deposit in Cangshan County is located in West Shandong Province, Southern Mountain-between white Yah block uplift and pottery dates faulted basin, Neo Archean Taishan group the Grass Valley group formation, the whole concealed ore deposits. The lithology is characterized by mainly bio- tite granulite, partial clip magnet, magnet amphibolite quartz hornblende quartz, biotite hornblende schist. The ore grade is low grade iron ore with typical metamorphosed sedimentary iron ore （Anshan）. The Cangshan county Ditch West-West Guanzhuang iron metallogenic geological background and geological characteristics of the depos- it, ore characteristics are analyzed. The metallogenic regularities are summarized. The further study about sedi- mentary metamorphic iron ore is of certain guiding significance.
