Abstract: The fluorite deposit in Muzhijie Area in Song County,Henan Province is located at the east of Machaoying deep fracture,the significant NE trending tectonic framework of the area is formed by Machaoying deep fracture.According to the field geological investigation results and the existing geological working results of the area,taking the NE trending structure of the area as an example,the characteristics and strength of orecontrolling tectonic activities,mineral composition,ore texture and structure,surrounding rock alteration characteristics of the fluorite deposit are discussed in detail,the spatial formation model of the fluorite deposit in Muzhijie Area is established,besides that,the spatial evolution regularity of the fluorite deposit in the area is also studied in depth.The above analysis results related to the orebody spatial formation and spatial evolution regularity of the fluorite deposit in Muzhijie Area in Song County,Henan Province can provide some reliable reference for further conducting prospecting and exploration work of fluorite deposit in the area.

Key words: Fluorite deposit, Orecontrolling structural characteristics, Orebody spatial formation, Orebody spatial evolution regularity
