| 摘 要： | 沂源县水磨头褐铁矿床赋存于刘家洞-水磨头断裂中,为小型褐铁矿矿床,矿区内矿体有呈脉状状产出;矿体规模较小,厚度、品位变化均匀。矿体长500m,平均厚度2.83m,控制斜深71.1m,TFe平均品位34.30%,品位变化系数15%,属品位变化均匀性矿体。断裂构造和围岩对成矿、控矿具有重要的作用,脉状矿体以充填作用为主。矿床成因属中低温热液交代充填—风化淋滤型矿床。

| Abstract: | Shuimotou limonite deposit in Yiyuan county occurred in Liujiadong-Shuimotou fault. The length of orebody is 500m, average depth is 2.83m, controlling slant depth is 71.1m, average grade is34.30%, and variation coefficient is 15%. It belongs to uniformity deposit of grade variation. Shuimotou deposit locates in Yiyuan county of Luxi area. It is a small type limonite deposit. Ore bodies in this area occurred in vein type. The scale of ore is small size with uniformity thickness and grade. The faulted structures and county rocks are very important to mineralization and ore-controlling factors. Infilling mineralization mainly happened in vein type ore bodies. The deposit is a low hydrothermal type deposits related to metasomatic filling-weathering. |
