摘要
矿床位于三江成矿域中甸成矿带,成矿条件优越。欠虽铁矿是通过磁异常扫面发现的矽卡岩型铁矿床。矿体受图姆沟组大理岩与浅成中酸性侵入岩接触带控制,Ⅰ号主矿体走向长940m,平均厚度39.88m,延伸稳定,边界未封闭,有较大的找矿潜力。矿床以Fe为主,伴生S、Cu、Pb、Zn、Au、Ag。矿石结构简单,铁矿品位富。高强度磁异常,褐铁矿、磁铁矿露头,矽卡岩和构造破碎带是主要的找矿标志。
The iron deposit is located in the Zhongdian metallogenic belt, Sanjiang metallogeny domain, which has excellent mineralization conditions. The ore bodies in the deposit mainly occur along the contact zone of the intermediate-acid intrusive porphyry （porphyrite） and Tumugou formation marble, which is belongs to skam type iron deposit. The length of I ore body is 940m and the average thickness is 39.88m with stable extension, the boundary is not closed, it has a considerable potentiality for prospecting. The ore deposit is mainly Fe, the associated elements of Fe are S.Cu,Pb,Zn,Au,Ag. The ore bodies are characterized by simple texture of ore and enrich grade. High-intensity magnetic anomaly, limonite, magnetite, skarn and structural fracture zone are the major prospecting criteria.
