摘要:
通过对保山地块黑牛凹金矿区内辉绿玢岩进行LA-ICP-MS原位微区锆石U-Pb定年和岩石地球化学特征分析,获得了辉绿玢岩的成岩年龄为(212.0±4.9) Ma,这一时限与核桃坪矿区内辉绿玢岩成岩时限(195.0±5.3) Ma,以及金厂河矿区辉绿玢岩成岩时限(217.3±5.8) Ma具有一致性,均属晚三叠世。黑牛凹辉绿玢岩具有低SiO2、低MgO及高钾特征,属于钾玄系列。微量元素具有富集轻稀土元素(LREE)、大离子亲石元素(LILE)及亏损高场强元素(HFSE)的特征,暗示其源区为岩石圈地幔。岩石中的Cr、Ni元素含量明显比原始玄武岩浆低,表明岩浆可能经历了橄榄石和辉石的结晶分离作用。Nb、Ta元素具明显负异常,暗示在岩浆上升侵位过程中受到了地壳物质的混染。黑牛凹辉绿玢岩形成的构造背景与区域内金厂河辉绿岩、核桃坪辉绿岩一致,均为板内拉张环境,这可能与古特提斯洋闭合导致保山地块因碰撞而发生的内部拉张、伸展活动有关。
