| 摘 要： | 洪福寺铁矿床处于济宁磁异常的北端,为隐伏矿床,埋深1000 m左右,赋存于新太古代济宁岩群浅变质岩中。该矿床发育11个铁矿体,矿体呈层状、似层状产出,产状与地层产状基本一致,探明的铁矿石资源量6.22亿t,平均品位TFe28.42%,mFe20.96%。矿床规模大、埋藏深,矿体形态和结构较简单,厚度较稳定,品位变化不大,矿石属于需选贫铁矿石。该矿床的勘探表明了分布于鲁西地区的新太古代济宁岩群存在较大规模的变质沉积铁矿,为该地区铁矿勘查开阔了空间。

| Abstract: | Hongfusi iron deposit locates in the north part of magnetic anomalies area of Jining city.It is a hidden deposit with the depth of around 1000m.It occurred in Archean Jining shallow metamorphic rocks.11 iron ore bodies developed in this deposits occurred in layered and quasi-layered types.The occurrence of ore bodies are consistent with the stratum.The already proven iron reserve is 622 million tons.Its average grade of TFe is 28.42%,while mFe is 20.96%.This deposit has the characteristics of large scale,deep buried ore bodies,simple ore shape and structure.Its thickness is stable with little change in grade.It belongs to poor iron deposit.The exploration of this deposit shows that there is big scale metamorphic sedimentary iron ores in Archean Jining group in western Shandong.It will provide more space for iron ore exploration in this area. |
