**1. Introduction**

Bureya-Jiamusi superterrane is a component of the Amur plate [10, 11, 24, 25, 33]. It is situated in the southern frames of Mongol-Okhotsk orogenic belt, which was formed as a result of closure of Mongol-Okhotsk orogenic belt. The structure of the Mongol-Okhotsk orogenic belt, closure time of the basin and, correspondingly, so is the structure-tectonical situation of the framing structures at that moment have no certain definition by the scientists. One of the most difficult and debatable structures of the region is Bureya-Jiamusi superterrane. A significant part of the superterrane body is situated in the territory of China, where it is actively studied by the scientists of the country [2, 12, 14, 19, 20, 39, 42, 44–47].

The northern border of the Bureya-Jiamusi superterrane is situated directly at the territory of Amur region (Russia) and correlates with its border with Mongol-Okhotsk orogenic belt [26]. According to [25], superterrane borders with Paleozoic early Mesozoic orogenic belts on west and south: South Mongol-Khingan, Solonker, Wundurmiao and China-Korea plate (**Figure 1**). The Bureya-Jiamusi superterrane situation by [19] is the same as by [25].

According to the idea, the spreading of the superterrane formations is significantly limited in the southwest direction [2, 12, 14, 20, 39, 40]. The author of the suggested article attempts to analyze the geodynamic processes in late Mesozoic-Cenozoic time, which could affect the

Previously, it was stated that the foundations of these terrains are the metamorphic complexes of the Archean-Proterozoic [17, 22]. But at this time, data on the age of protoliths of

According to the data, the formation of the foundation occurred not earlier than late Proterozoic. Superimposed structural-metamorphic transformations are connected not with the Precambrian events but are the result of processes that occurred in the territory of Bureya-

It is believed that the Paleozoic granites along with Devonian, Permian, and Silurian volcanogenic and terrigenous formations played a "stitching" and overlapping role in the structure

They built up more ancient formations. In turn, they were blocked and injected with Mesozoic rocks (Triassic and Cretaceous) [16]. According to the research results of the biota characteristics from terrigenous deposits of early Mesozoic (Triassic-Jurassic) of Bureya-Jiamusi superterrane, it was stated that the rocks were formed in the sea basin under conditions of significant climate changes. Such changes are characteristic of mid-latitude [21]. The formations of the Sikhote-Alin terrains that are the neighboring territory at the east were formed under tropical conditions of the marine environment of low latitudes. With all that, it was shown that the sedimentation accumulation of the rocks occurred in the single oceanic basin [21]. As the authors consider, the fact is "an important, evidence in favor of the interpretations, according to which, a number of Sikhote-Alin terrains, experienced large-scale displacement in the northern direction" [21]. Shallow marine sediments, which are replaced by coarse continental material, begin

to form in Jurassic. The end of Jurassic is marked with magmatic activity in the region.

**2. Geological structure of the Bureya-Jiamusi superterrane**

As the author states [19], the southern border of superterrane is cut by Suolunshan-Central Jilin orogenic belt, which is an intermediate suture between the superterrane and the China-Korea plate. Li [19] suggests that Solonker orogenic belt includes the Bureya-Jiamusi superterrane in its structure. But there are also other ideas of the location of the Bureya-Jiamusi superterrane (**Figure 1**).

According to the idea, the spreading of the superterrane formations is significantly limited in the southwest direction [2, 12, 14, 20, 39, 40]. The author of the suggested article attempts to analyze the geodynamic processes in late Mesozoic-Cenozoic time, which could affect the structure-tectonical formation of Bureya-Jiamusi superterrane.
