摘　　要：陕西平利大磨沟锌、萤石矿床和区域上已发现的金、铅锌、铌、钽等金属矿产、萤石等非金属矿产与该区域及邻区粗面质岩类关系密切,矿化产于中志留统竹溪群千枚岩与碱性粗面岩断层接触带碱性粗面岩一侧,成矿受断裂构造控制,属岩浆期后热液矿床。区域上平利复背斜的东翼大面积粗面质岩类出露,以其为赋矿岩石的矿种较多,具有较为重要的找矿意义,笔者就其特征及外围找矿前景进行了总结分析。Pingli Damogou zinc-fluorite depositin in Shaanxi and metal minerals of gold, lead, zinc, niobium and tantalum and nonmetal mineral fluorite, etc, already found in this region, have a close relationship with the trachyte in this area and neighbor area. Mineralization is in contact with faulting of Middle Silurian Zhuxiqun Formation phyllite and trachyte, and is near the trachyte side and controlled by faulted structure, belonging to post-magmatic hydrothermal ore deposits. Regionally, a large area of rachyte exposed to the east wing of Pingli anticlinorium results in numerous ore-hosting rocks for minerals, having an important significance in prospecting.
