英文摘要	It has been revealed that most world-class porphyry copper and epithermal gold deposits of Cenozoic age around Pacific Rim, such as those occur-red in the Central Andes and the Philippines, are spatially and temporally associated with contemporaneous adakitic magmatism. Adakite and its clan (such as high magnesian andesites (HMA), magnesian andesite (MA), Niobium-enriched basalts (NEB), and high Niobium basalts, etc.) are the host rocks of most porphyry copper deposits, and the source rocks of many epithermal An systems. Based on the present level of understanding, the genetic relationship between them may stem from the inherent natures of adakitie magmas with sufficient fluids, high oxygen fugacity and mafic source region, which are preferred for Cu, An and other deeply-sourced metals to be extracted and enriched, and finally economically mineralized. However, the reason (s) and mechanism responsible for this relationship are poorly understood in general. It is suggested that the close link of adakites with porphyry copper and epithermal gold deposits be a potential metallogenetic specialization of magmatism that necessitate in-deep assessment and relevant comparative studies among ore-bearing adakites, barren adakites and normal calc-alkaline rocks, to uncover the intrinsic and concealed story.
