摘　　要：渣滓溪—羊皮帽地区是雪峰弧形成矿带重要组成部分,区域性北东向马家溪断裂(F_(1))、岳溪断裂(F_(2))和烟溪断裂(F_(3))、连里断裂(F_(4))组成两组“断裂对”控制两个北东向矿带,其间一系列短轴复式背、向斜及逆冲断层组成典型的断块式构造控制矿床,且受区域性北东向断裂构造及深部隐伏岩体的控制,自岩体往外,南西往北东形成锑金钨—锑钨—锑金分带。本文以雪峰弧形构造带北东段金锑矿成矿预测研究与靶区优选对渣滓溪—羊皮帽地区调查为基础,阐述了两个矿带内典型矿床特征,分析了矿产空间分布规律和成矿地质条件,指出了找矿标志及找矿远景区域,对本区乃至雪峰弧形成矿带找矿有一定的指导作用。Zhazixi-Yangpimao area is an important part of Xuefeng arc forming ore belt,The"Fault Pairs"of Regional NE-trending of Majiaxi and Yuexi,Yanxi and Lianli controlled two NE-trending ore belts.A series of short-axis compound anticline,syncline,thrust and thrust faults between them constitute a typical fault-block structure-controlled deposit.It is also controlled by regional NE-trending fault structure and deep buried rock mass.The zoning of Antimony-gold-tungsten ore to Antimony-tungsten ore to Antimony gold ore is formed from the outside of the rock mass and from southwest to northeast.This paper is based on the investigation of Zhazixi-Yangpimao area in the research project of Study on metallogenic prognosis and optimization of metallogenic target area of Gold-antimony deposit in the northeast section of Xuefeng arc structural belt.Expounded the characteristics of typical deposits within the two metallogenic belts.Analyzed the spatial distribution law of minerals and metallogenic geological conditions.Pointed out The prospecting criteria and prospecting potential areas.It has a certain guiding role for prospecting in this area and even the Xuefeng arc forming ore belt.
