【Abstract】 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.更多还原
