The conditions for the formation of Paleogene-Neogene metalliferous coals in a setting of tectonic movement intensification in the zone of junction between the Turan massif and Zeya-Bureya basin have been studied. The massif with the Selemdzha-Tomsk and Arkhara grabens separated by the Bureya horst and bounded by the systems of northeastern strike-slip faults was found to have a keyboard structure. The research showed that the most favorable conditions for the ore microcomponent accumulation in coals through the erosion of the Late Cretaceous ore-bearing chemical residue were within the submerged blocks of the massif. The paleodrainage system carrying microcomponents drained the grabens and the associated sedimentary sub-basins of the Zeya-Bureya basin eastern margin. Ore components were transported mainly in solution and as solid clasts to the areas of coal accumulation as evidenced by the resemblance of the elementary composition of coals in the Zeya-Bureya basin and geochemical anomalies of the Turan massif.

The concentration, speciation, and localization of rare earth elements in Miocene brown coals from the Sergeevskoe deposit (Amur oblast) have been studied. The total rare earth element content of the test coals (97.43 mg/kg) exceeds the clarke value by a factor of 1.5; the amount of light lanthanides (74.57 mg/kg) prevails over that of heavy ones (7.68 mg/kg). The main concentrators of lanthanides in Miocene brown coals are humic acids. The amount of rare earth elements in water-soluble, ion-exchange, silicate, and disulfide forms does not exceed 5% of the total content with the exception of scandium, 22% of which is associated with silicate minerals such as clays.

The formation of metal-bearing coalfields of the Raichikhinskoe deposit in the conjugation zone of distributive provinces of the Bureya uplift and coal-accumulation areas of the Zeya–Bureya sedimentary basin was studied. It was established that it occurred under conditions of the successive extraction of ore components from weathering crusts of the Bureya uplift, transportation, and unloading in the paleodelta of the Bureya River. These processes proceeded synchronously with volcanic activity in the Sikhote-Alin orogenic belt, which is associated with the supply of volcanic ash. The association of these events made it possible to distinguish two types of enrichment of the Raichikha coals in rare earth elements and yttrium (REY): terrigenous with the supply of REY by surface waters and combined terrigenous volcanogenic associated with the shedding and leaching of acidic and alkaline volcanic ash. The cerium group lanthanides predominate in coals and their combustion products. The largest fraction of REY was contained in fly ash (0.11% on a total weight basis). The mechanisms of accumulation of ore components at the stage of peat deposits are considered from the standpoint of the localization of trace ore components as clastogenic mineral forms and under the conditions of interaction of ore solutions with the organic environment of peat bogs. The quality of REY was assessed, and the most enriched sections of the Verkhnii layer were identified. Prospects for the extraction of lanthanides from coal are considered from the standpoint of the possible recovery of a number of rare, nonferrous, and noble metals in this process.
