摘　　要：河南南召神仙崖饰面用花岗岩矿床位于秦岭造山带东部,成矿区带属于东秦岭—大别成矿带。五朵山岩体中黑云母二长花岗岩类为矿床赋矿母岩,矿区内圈定饰面用花岗岩矿体1个,探获饰面用花岗岩矿石量1672.70×10^(4)m^(3),荒料量515.66×10^(4)m^(3)。通过对神仙崖饰面用花岗岩矿床地质特征与矿体特征分析,确定矿体形态简单,连续性好,厚度稳定,深部岩石完整性好。初步分析了矿石物理性能与加工技术性能,总结了成矿规律,其成因类型为岩浆矿床,成矿时代为加里东期。该矿床的发现及研究对今后东秦岭造山带寻找同类型饰面石材矿床具有一定的借鉴意义。Nanzhao Shenxianya facing granite mining area is located in the eastern Qinling orogenic belt.The metallogenic belt belongs to the East Qinling-Dabie metallogenic belt.The biotite monzogranite unit in Wuduoshan rock mass is the parent rock of ore deposit.One granite ore body for decorating surface in the mining area.The amount of granite ore used for surface decoration is 1672.70×10^(4)m^(3),and the amount of waste material is 515.66×10^(4)m^(3).Through the analysis of the geological characteristics and ore body characteristics of the granite ore used for the decoration of Shenxianya.It is determined that the ore body is simple in shape,good in continuity,stable in thickness and good in deep rock integrity.Preliminary analysis of physical properties and processing technology of ore.The metallogenic regularity was summarized.The genetic type of the deposit is magmatic deposit.The metallogenic epoch was Caledonian.The discovery and research results of this deposit have important reference significance for the exploration of the same type of facing stone deposits in the East Qinling orogenic belt in the future.
