摘要
经山寺矿床是舞阳铁矿田内的三大矿床之一。目前,在经山寺矿区500 m以上已探明资源储量22 409万t,其外围仍有较大的找矿潜力。根据矿体的基本地质特征和构造变动特点,分析该区矿床成因类型、找矿潜力和找矿方向,为该区找矿工作提供理论支撑,并达到实现找矿重大突破的目的。研究认为,矿床是在滨海环境下直接沉积形成的,矿床类型为与绿岩带有关的阿尔戈马型条带状建造铁矿床。在矿区已控制的范围内,矿层继续向深部延伸且厚度无变薄趋势;另外,矿区西侧外围及南侧500 m以下仍有较大的找矿空间,下一步找矿方向应锁定在经山寺至铁山矿区的15 km范围内,以及从舞钢市姚庄至叶县南房庄20 km内的三角地带。
Jingshansi iron deposit,one of the three largest deposits in Wuyang iron ore field,whoes proven reserves above 500 m reaches 224.09 million tons,still has a large prospecting potential in its periphery.We analysis area genesis of the type of prospecting potential and exploration direction,according to the basic geological eharacteristics of the orebody and tectonism feature,to provide theoretical support for the prospecting work in the area,and also to achieve the purpose of major break through in prospecting.Study results suggest that the deposit is formed by direct deposition in a coastal environment,its deposit type is the Algoma-type banded＇ iron construction with greenstone belts iron deposit.In the mining area has been controlled,the seam is continue extending to the deep with the trend of no thinning; and there is large prospecting potential outside the west side of the mining area and under 500 m in the south side, prospecting direction should be focused within the 15 km area between the Jingshansi to the Tieshan mine area, and the 20 km triangle area between Yaozhuang（Wugang City） and Nanfangzhuang （Ye county）.
