@@@@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.
