摘要
内蒙古地区阿德格哈善图萤石矿床赋存于下二叠统大石寨组三岩段底部的结晶灰岩中,属于碳酸盐岩地层中的层控型矿床,严格受层位控制,其成因为火山沉积-改造型。矿区位于西里庙向斜南东翼,区内呈单斜构造,矿区内大石寨组二、三岩段间发育层间断层,是矿区内的控矿和容矿构造;矿区矿石按矿物组分划分属于石英-萤石型,按结构构造划分主要有纹层状、细晶块状、网格状、晶簇状萤石矿石。
Fluorite mineral resources are abundant in Inner Mongolia Autonomous Region.Adegehashantu fluorite deposit occurs in the crystalline limestone at the bottom of the third rock member of The Lower Permian Dashizhai Formation.It belongs to stratabound deposit in Carbonate stratum.The deposit is strictly controlled by horizon.Its formation is due to volcanic sedimentation-reworking type.Mining area is located in southeast wing of Xilimiao syncline.The structure is monoclinal.Interlayer faults are developed between the second and third rock members of Dashizhai Formation in the mining area.It is the ore-controlling and ore-hosting structure.The ore belongs to quartz-fluorite type by mineral composition.According to the structure,it is mainly divided into lamellar,fine crystal massive,grid vein and crystal cluster fluorite ores.
