Abstract: Most of the plutonio masses in northeastern Asia were emplaced in the late Mesozoic. They exhibit a wide range of compositions and, on the basis of ranges, the batholiths form two groups, one acidic with a narrow range from granodiorite to granite, and the other with a wide range extending from gabbro through diorite and tonalite to granodiorite and granite. The Verkhoyansk-Chukchi region, with its Preriphean crust, is characterized by the acidic series, as are miogeosynclinal regions in general. The gabbro-granite series is typical of eugeosynclines such as the northeast-trending Okhotsk-Chukchi volcanogenic belt.
