河南方城县庵沟饰面花岗岩矿床地质特征浅析

Geological Characteristics of Angou Ornate Granite Deposit in Fangcheng County,Henan Province

河南省方城县庵沟饰面用花岗岩矿地处华北陆块南缘与秦岭造山带结合部位,区内沉积建造独特、岩浆活动频繁、构造变形强烈。早白垩世黑云母二长花岗岩类为矿床赋矿母岩,矿体形态简单,厚度稳定,岩石完整性好,荒料率高。矿石的物理性能满足饰面石材技术要求,装饰性强。该矿床的开发,将进一步推动该区建筑材料工业的发展,同时对于同类型饰面石材矿的开发具有一定借鉴意义。

The Angou granite mine for decorative use in Fangcheng county,Henan province is located in the combination of the southern margin of the North China landmass and the Qinling Orogenic belt,which has unique sedimentary formation,frequent magmatic activity and strong tectonic deformation.Early Cretaceous biotite monzonitic granites are ore-bearing parent rocks with simple ore body,stable thickness,good rock integrity and high waste rate.The physical properties of the ore meet the technical requirements of the facing stone,and the decoration is strong.The development of this deposit will further promote the development of building material industry in this area,and has certain reference significance for the development of the same type of facing stone ore.
