摘要:
辉森乌拉西金矿位于阿拉善地块北缘,是一处具有大型规模远景的金矿床,探讨该金矿床的成矿特征和成矿模式具有重要的地质意义。通过对矿床地质特征和区域地球化学特征的分析,结合微量元素分析及流体包裹体研究,对矿床成因和成矿模式进行了初步探讨。元素地球化学特征及微量元素分析显示研究区为一高背景的金地球化学块体,二叠系哈尔苏海组为矿源层。流体包裹体研究表明金矿形成于中温(240~260 ℃)环境,成矿流体为低盐度、低密度流体。区内褶曲、揉皱、片理化带和构造蚀变带为金矿床的导矿及容矿构造。金矿成因类型为受中温岩浆热液影响的蚀变岩型金矿床,成矿模式为古蒙古洋壳向阿拉善地块俯冲时引发Au元素活化富集并形成矿源层,晚二叠世岩浆侵入时金活化、迁移最终富集成矿,后期受构造变形和风化剥蚀作用影响发生次生富集。
