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。
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 de-posit locates in Yiyuan county of Luxi area. It is a small type limonite deposit. Ore bodies in this area oc-curred in vein type. The scale of ore is small size with uniformity thickness and grade. The faulted struc- tures and county rocks are very important to mineralization and ore-controlling factors. Infilling minerali-zation mainly happened in vein type ore bodies. The deposit is a low hydrothermal type deposits related to metasomatic filling-weathering.
