摘　　要：通过对四川盐源西范坪地区斑岩群地质特征、形成时代、侵入期次、岩性特点及岩石化学及微量元素地球化学的综合研究,讨论了区内含矿与不含矿斑岩的岩相学及地球化学特征,进而提出了本区斑岩铜矿的成矿专属性及找矿标志。Based on the comprehensive studies on the geology, ages, intrusive periods, lithology, lithochemistry and geochemistry of trace elements of porphyries in the Xifanping area, Yanyan, Sichuan, the lithofacies and geochemistry for both ore-bearing porphyries and barren porphyries are discussed. Finally, their specialization for copper mineralization and ore-searching criteria is inquired into.
