| 摘 要： | 荷花山铅锌矿床是长江中下游成矿带铜陵矿集区内新发现的大型铅锌矿床,该矿床矿体呈似层状主要赋存于三叠系南陵湖组下段瘤状灰岩中。矿区内经钻孔揭露,有两种岩性的闪长岩类,分别为矿区西侧的闪长岩体和东侧的石英闪长岩体。锆石LA-ICP-MS U-Pb年代学分析得出这两个岩体的年龄分别为133.0±2.1Ma和130.1±1.7Ma,表明其形成时代为早白垩世。全岩地球化学分析显示,荷花山闪长岩类表现为Si O256%(56.17%~65.90%),Al2O3≥15%(15.10%~17.22%),Mg O3%(0.84%~2.22%),Yb1.9×10~(-6)(1.35×10~(-6)~1.64×10~(-6)),Y18×10~(-6)(11.60×10~(-6)~15.70×10~(-6)),无明显的Eu异常等特征,具有与典型的埃达克岩相似的特征,微量元素判别图解表明荷花山矿区闪长岩类岩浆来源于幔源岩浆和加厚下地壳埃达克岩浆的混合,是铜陵地区晚期岩浆活动的代表;构造判别图解表明荷花山闪长岩类形成于相对挤压或者挤压向拉张过渡的岩石构造环境,其形成与古太平洋板块的俯冲有关,可能预示着铜陵地区存在130Ma左右的铅锌矿化事件。
