摘要
沂源县境内重喜官庄矿区方解石矿是山东省目前探明的最大的方解石矿,矿区内有矿体2个,均呈脉状充填于NW向的断裂构造带中;矿体属大型规模,厚度、品位变化均匀;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。矿床成因属低温热液充填型矿床。
Calcite deposit in Chongxiguanzhuang mining area in Yiyuan county is the largest calcite deposit proved in Shandong province. There are two ore bodieds in the mine which are showed as band type and filled in the frac- ture structure with the trend of NW. Ore bodies are large size with average thickness and grade change. Fracture structures and surrounding rocks play an important role in mineralization and ore - controlling. Filling is the main function in vein type ore body. The origin of this deposit belongs to low temperature hydrothermal filling type depos- it.
