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 deposit is located in Zhongdian metallogenic belt of Sanjiang and has superior metallogenic conditions. Although the iron ore is owed by the magnetic anomaly scanning surface skarn type iron deposits found. The ore body is controlled by the contact zone between the marble of the Tumugu Formation and the intermediate-acid acid intrusive rock. The main ore body of No. 1 is 940m long and has an average thickness of 39.88m. The main ore body extends steadily and the boundary is not closed and has great prospecting potential. The deposit is dominated by Fe with accompanying S, Cu, Pb, Zn, Au and Ag. Ore structure is simple, rich iron ore grade. High-intensity magnetic anomalies, limonite, magnetite outcrops, skarns and tectonic fractures are the major mineral prospecting indicators.
