摘　　要：牛头寨锑矿位于华南褶皱系北缘,湘中、湘南印支褶皱带、祁阳弧形褶皱构造带西部,区域成矿条件优越。为解决牛头寨地区的深部找矿问题,在总结矿床地质特征的基础上,通过控矿因素分析,得出“背斜+断裂+岩性”的控矿规律,且矿化受断裂分带影响。结合矿床成因的分析探讨,建立了成矿模式,预测大瓜冲、大硐子及线江冲区段往北深部具较好的找矿远景。Niutouzhai antimony deposit is located in the northern margin of South China fold system,the Indosinian fold belt of Central and South Hunan and the west of Qiyang arc fold structural belt.The regional metallogenic condition is favorable.In order to solve the deep prospecting problem in Niutouzhai area,on the basis of the summary of the geological characteristics of the deposit and the analysis of ore controlling factor,the ore controlling regularity of"anticline+fault+lithology"is found out,and the mineralization is affected by the fault zonation.Combined with the analysis and discussion of the deposit genesis,the metallogenic model is established,and it is predicted that there is a good prospecting prospect in the north areas of Daguachong,Dadongzi and Xianjiangchong sections.
