摘　　要：甘肃省红柳峡萤石矿位于金塔-额济纳旗萤石矿成矿带中,该地区构造—岩浆活动强烈,发育大量华力西多期火山岩及中酸性侵入岩;通过对红柳峡萤石矿地质矿产特征分析研究,认为该地区岩浆活动和区域性及其次级断裂构造是主要控矿因素,岩体中的北北东向、北北西向次级张扭性断裂构造是重要的矿液聚集成矿场所;总结建立了本地区萤石矿的找矿标志;认为矿床成因为岩浆期后中—低温热液(充填)型。可为本地区萤石找矿工作提供借鉴指导作用。The fluorite ore deposits in Gansu Province,specifically those in the Hongliuxia region,are situated within the broader Jinta-Ejinagi Banner fluorite ore mineralization belt.This region is characterized by a high level of tectonic and magmatic activity,which has led to the development of numerous multi-phase volcanic rocks and neutral acidic intrusive rocks.The geologic and mineralogical characterization and analysis of the Hongliuxia fluorite ore region,conducted by this study,suggests that the region's magmatic activity and the regional and its secondary fracture tectonics are the primary mineral control factors.The geological and mineral analysis of the Hongliuxia fluorite mine,conducted by this study,It is postulated that magmatic activity and the regional and secondary fracture structure are the primary factors controlling ore formation in the area.The north-north-east and north-north-west secondary torsional fracture structure within the rock body represents a crucial site for the aggregation of mineral fluids,leading to the genesis of ore.The search markers for the fluorite mine in the area were summarized and established.It was concluded that the ore deposits were formed as a result of a medium-low-temperature hydrothermal fluid(filling)type after the magmatic period.This study can serve as a reference point and provide guidance for the search for fluorite in this region.
