Popis: The distribution of the mass centers and rheological heterogeneity of sources inducing gravity anomalies in the Okhotsk massif and its surrounding structures are analyzed. The structures of the metamorphic basement of the massif and overlying folded and volcanic complexes are defined and 3D parameterized. It is shown that the massif was primarily an element of the North Asian craton and its subsurface metamorphic complexes occupy now the allochthonous position in the crust section. It is established that fold structures and the granite-metamorphic layer of the crust demonstrate features of inherited interrelations under the volcanic cover. The tectono-magmatic structure of the central type defined in the lower reaches of the Okhota and Inya rivers is described in the 3D space.
