摘要
云南新平鲁奎山地区铁矿床总体上可分成两种类型,一是矿体呈似层状、层状赋存于昆阳群大龙口组下部(Pt_(2)d^(1))及富良棚组(Pt_(2)f^(2))上部,其显示了沉积-改造型矿床的特征;另一种是矿体为脉状、大透镜状赋存于断层破碎带内,显示了热液型脉状矿床的特点。该地区铁矿明显受层位、构造、岩浆岩三重因素控制。
The Fe deposits in Lukuishan area of Xinping,Yunnan generally can be divided into 2 types:1.The orebody is stratoid,bedded in Kunyang Group Dalonou Formation lower part(Pt_(2)d^(1))and Fuliangpeng Formation upper part(Pt_(2)f^(2)),showing the feature of sedimentation-reformation type deposit;2.The orebody is veined,large lenticular in fault fracture zone,showing the feature of hydrothermal veined deposit.The Fe deposit in this area is controlled evidently by the 3-factor of horizon,structure and magmatic rock.
