| 中文摘要: |
| 镇康县小河边铁矿位于镇康县以东，保山—镇康地块南端，受区域性的北东向南汀河断裂带和镇康复背斜控制，属三江成矿带中南段之保山—镇康铅锌铜铁金成矿带芦子园亚带。小河边铁矿含矿地层为寒武系沙河厂组二、三段，矿体产于矽卡岩带中，基本沿北东向断裂展布。矿体走向北东，倾向北西，倾角46°83°，呈脉状、似层状产出，赋矿岩石为阳起石矽卡岩，局部为辉绿岩。通过对矿床的研究，认为该矿床的成因为矽卡岩型铁矿床，在矽卡岩带及磁异常带是良好的找矿标志。 |
| 英文摘要: |
| Xiaohebian iron ore mine located in Zhenkang County to the East, mine is located in the south of Baoshan-Zhenkang Massif, controlled by regional ne nanting River fault zone and the town recovered anticline, belong to the Luziyuan subzone of Baoshan-Zhenkang lead, zinc, copper, iron and gold metallogenic belt in the middle and south Sanjiang metalloegnic belt. The ore-bearing stratum of Xiaohebian iron deposit is the section 2 and 3 of Shahechang formation in Cambrian, the orebody occurred in skarn belt and spread along NE direction. The orebody strike NE and trend NW, the dip angle is 46°83°, occurs as vein and bedded, the hosted rock is actinolite scarn, some is diabase. By study the deposit, it’s thought that the genesis of this deposit is scarn iron deposit, the scarn belt and magnetic abnormal belt are the good propspecting signals. |
