摘　　要：安徽凤凰山矿田为铜陵矿集区典型矿田,该矿田万迎山发现的铅锌(铜)矿体与以往的矽卡岩型矿体有显著区别。通过区域地质资料比对、见矿工程编录、成矿构造解析、元素相关性分析等方法手段,厘定了构造-热液型铅锌(铜)矿、矽卡岩型铜矿2种类型,前者晚于后者,为铜陵地区存在晚于铜矿化的铅锌矿化提供了证据。凤凰山断裂带的多期活动起到了导矿、容矿、破矿构造作用,该断裂带及与其交会的北东向层间断裂带均具有良好的找矿前景。The Fenghuangshan ore field is a typical ore field in Tongling ore concentration area.The Wanyingshan lead-zinc(copper)ore body discovered in this study area is significantly different from previous skarn ore body.Through regional geological data comparison,drill hole information recording,ore-forming structural analysis,elemental correlation analysis and other measures,two types of ore bodies of structure hydrothermal lead-zinc(copper)ore and skarn-hosted copper deposits were determined.The earlier formation of the former type provides evidence for the later appearance of lead-zinc mineralization than copper mineralization in Tongling area.The multiphase activity of Fenghuangshan fault zone plays the role of mineral transfer,mineral deposition and mineral destruction.The Fenghuangshan fault zone and its intersected NE-trending interlayer fault zone have good prospecting prospect.
