摘要
河南省桐柏县岭上萤石矿位于华北克拉通南缘萤石矿成矿带内。萤石矿体产出于早白垩世花岗岩与地层接触附近的构造破碎带中,地层对萤石矿体的成矿控制作用不明显,断裂构造控矿作用显著,NNW向和NW向断裂构造为矿区主要控矿构造,早白垩世岩浆活动为成矿作用提供了能量和物质来源。本区沿银洞沟组地层与铜山岩体的NNW向和NW向断层破碎带是重要的找矿方向,区域上圈定的F异常区也是较好的找矿部位。
Lingshang fluorite deposit,Tongbai County,Henan Province is located in the fluorite mineralization belt on the southern edge of North China Craton.The fluorite ore body is hosted in the tectonic fracture zone near the contact between the Early Cretaceous granite and the strata.The ore-controlling effect of the strata on the fluorite ore body is not obvious,and the ore-controlling effect of fault structure is significant.NNW and NW fault structures are the main ore-controlling structures in the mining area,and the Early Cretaceous magmatic activity provides energy and material sources for mineralization.The NNW and NW fault fracture zones along Yindonggou Formation and Tongshan rock mass in this area are the important prospecting direction,and the F anomaly area delineated in the area is also a good prospecting location.
