摘要
山东金乡县羊山铁矿床赋存于泰山岩群山草峪组,铁矿石推断资源量1180.1万t,矿床平均品位TFe29.49ω%,mFe20.81ω%,具有较好的找矿前景和潜力。本文采取面上地质调查、物探剖面测量、深部钻探验证及样品测试等工作手段,对成矿地质背景和矿床地质特征进一步研究,认为矿床成因主要是先沉积成岩,后经热液侵蚀变质成矿。为羊山铁矿深部和外围找矿指明了方向。对周边地区和其他相似地区寻找铁矿提供了重要的参考。
Yanghshan Fe deposit in Jinxiang,Shandong is in Taishan Lithologic Group Shancaoyu Formation,the inference Fe ore 11.8 Mt,average grade TFe 29.49%,mFe 20.81%,with the good prospecting potentiality.In this paper,according to the areal geological survey,geophysical section survey,deep drilling examination and sample testing,etc,we have studied further on metallogenesis geological background and feature and we think it is mainly sedimentation diagenesis at first,then hydrothermal alteration metallogenesis,which point out the prospecting direction in deep and surrounding of Yangshan Fe deposit,provide important reference for Fe deposit prospecting in other similar area.
