A Jurassic accretionary prism in the Sikhote-Alin-Amur area is an assembly of terranes which are tectonic-sedimentary complexes consisting of multiple strongly deformed fragments of an oceanic plate. The stack of tectonic-stratigraphic units (complexes) in the prism section records its geodynamic history, each unit being signature of a geologic event on the Paleoasian eastern margin. The succession of accretion events brought together fragments of a Paleozoic oceanic plateau in the Early Jurassic and abyssal plain fragments of different ages in Middle and Late Jurassic time
