| 中文摘要: |
| 舞阳铁矿是一超大型矿床,共提交资源量超过11亿t。采用对岩性和副矿物特征、地质状态、岩相学标志分析以及岩石测试的方法,得出了铁山庙组铁矿层的下盘地质体原岩为石英砂岩或长石石英砂岩、经变质作用而形成白粒岩的沉积变质成因。研究区铁矿分布面积高达50多平方千米,由于受深度和地质演化的影响,已进行过勘查的区域仅占约20%,在其深部仍有较大的找矿空间。 |
| 英文摘要: |
| Wuyang iron deposit is a super large deposit with a total resource reserve of more than 1.1 billion tons. In order to correct the misjudgment of igneous rock origin of the underlying geological body of Tieshanmiao formation iron ore bed, which was considered to be the intrusive formation of the white granite in the previous prospecting practice, to connect the ore body correctly. The author adopts the methods of lithology and accessory mineral characteristics, geological state, petrographic mark analysis, and rock testing. It is concluded that the underlying geological body of Tieshanmiao formation is the result of sedimentary metamorphism of leptie formed by metamorphism of quartz sandstone or feldspar quartz sandstone. The distribution area of iron ore in the study area is more than 50 square kilometers. Due to the influence of prospecting depth and geological evolution, only about 20% of the area has been explored. There is still a large prospecting space in the deep part of the area. This paper will have some guiding significance for the future prospecting work in this area. |
