Реферат:	eng: The Late Albian-Early Cenomanian epoch of Au-Cu porphyry ore mineralization has been distinguished within the Sikhote-Alin. The development of ore mineralization is associated with Albian-Cenomanian granitoids, synchronous to syn-strike-slip orogenesis and the formation of the continental lithosphere in the setting of transform continental margins. The development of Au-Mo-Cu and Cu-Au-W types of ore mineralization in the terrains of the Jurassic accretionary prism and the Early Cretaceous terrain of the epioceanic turbidite basin, correspondingly, was induced with the mantle-crustal synorogenic intrusions of granitoids. The U-Pb zircon dates (100-95 Ma, Albian-Cenomanian) of Au-Cu porphyry Malmyzh granitoids are given for the first time. The similar data available on the age of granitoids in Eastern and Southeastern Asia, which are associated with plutonogenic-hydrothermal deposits of Cu, Au, Sn and other metals, allow us to suggest that there is an Albian-Cenomanian metallogenic megabelt extending along the entire Pacific continental margin of Asia.
