determinations for the terrains of the Sikhote-Alin orogenic belt structures bordering the superterrane from the east [9, 28, 29] showed that they were much more south of the 30th parallel 123 ± 22 Myr. All this confirms the assumption that Bureya-Jiamusi superterrane was located at a considerable distance from its current location and was an independent geological object in late Mesozoic. Any magmatic activity in the Bureya-Jiamusi superterrane is

**Figure 3.** Hypothetical scheme of the spatial position of the Bureya-Jiamusi superterrane, compiled from original data and materials [2, 12, 25, 31, 39, 43]. Areas of distribution of rocks of late Mesozoic volcano-plutonic complexes: (1–2) differentiated and bimodal: mainly plutonic (1), mainly volcanic (2); volcano-plutonic complexes of Bureya-Jiamusi superterrane; (3–5) with the late Jurassic age—135 Myr (3), 120–105 Myr (4), 101–99 Myr (5). The boundaries of superterrane (6–7): subduction boundaries (6), transforming boundaries (7). Age of the magmatic rocks (8). Other tectonic boundaries (9).
