摘要(Abstract)：

黑云母是花岗岩中最常见的暗色矿物，其成分特征可以指示岩石成因和成矿环境。薄竹山雷达站花岗岩中黑云母矿物化学成分表明该花岗岩中的黑云母属于铁镁质黑云母，Ti温度计计算的黑云母结晶温度为665～756℃，结晶氧逸度介于-12～-16之间，其固结压力为98.44～386.29 MPa，对应的形成深度为3.72～14.60 km，表明薄竹山雷达站花岗岩形成于中深成环境。w(Al_2O_3)含量高以及原生白云母的出现表明该花岗岩可能属于S型花岗岩。黑云母中w(MgO)含量为7.52%～9.99%，镁质率（I_(Mg)）为0.41～0.50，氧化系数为0.075～0.167，以及Mg/(Fe⁽³⁺⁾+Fe(3+)+Fe⁽²⁺⁾+Mg+Mn)值>0.38均指示雷达站花岗岩兼具I型花岗岩的特征，雷达站花岗岩岩浆源区具有壳幔混合的特点。中高温及低氧逸度的成岩环境有利于W、Sn矿床的形成，I型花岗岩的特点利于Cu、Pb、Zn、Ag矿床的形成。
