摘　　要：湘西北地区广泛发育石英脉型金矿。在马家坡一带,发育独具特色的钠长石-石英脉型金矿床。本文在总结前人研究的基础上,结合在马家坡金矿一带多年勘查的工作经验,从区域地质背景、矿区地质特征等方面简要介绍了马家坡金矿床总体地质特征,并粗略探讨了该区围岩蚀变与金矿化的关系,同时通过类比邻区的合仁坪金矿,简析了矿床成因,以期今后对本区及周边的找矿勘查工作提供一定参考。Quartz vein type gold deposits are widely developed in northwestern Hunan.In the Majiapo area,unique albite-quartz vein type gold deposits have developed.Based on previous studies and combined with years of exploration work experience in the Majiapo gold mine area,this article briefly introduces the overall geological characteristics of the Majiapo gold deposit in terms of regional geological background and geological characteristics of the mining area,and roughly discusses the surrounding rocks of the area.The relationship between alteration and gold mineralization,at the same time,through the analogy of the Herenping gold mine in the neighboring area,briefly analyzed the genesis of the deposit,in order to provide a certain reference for the prospecting and exploration work in this area and its surrounding areas in the future.
