Based on a study of several sections of the Taukha terrane in southern Sikhote-Alin comprising lithologic, structural and paleontological analysis, the structure and stratigraphy of the terrane was reconstructed. Three structural units are defined for the terrane, each with a discrete origin. Each unit consists of a paleo-oceanic plate formations gradually changing above on a section by terrigenous rocks, which are further replaced by an olistostrome. Radiolarian age data for the accretionary prism indicates that fragments of a late Devonian-Permian, Early Triassic-Late Jurassic and Late Jurassic-Early Cretaceous paleo-oceanic plate were consecutively accreted into the prism.
