“…The ratio of the contents of light REE over the heavy is used for genetic interpretations of the sources of terrigenous material transported to the area of coal-forming peats in the Paleocene (Sorokin et al., 2019). For coal and the host rocks of the Yerkovetskoe deposit, it is in the range of 7.64–9.9, which is determined by the scale of development of effusive and granitoids in the sources of demolition.…”

Major, trace, rare-earth elements, and noble metal have been analyzed from the brown coal of the Amur region (Russian Federation) and coal combustion products to understand the provenance and depositional environment. It was discussed that weathering crusts of ore deposits and host rocks located in the mountain-folded frame of the Zeya-Bureya coal-bearing sedimentary basin were the main source of mineral substance and chemical elements in brown coals. The distribution of minerals and elements inside the forming coal seams was influenced by the type of vegetation incorporated into coal-forming peat mires bog by catastrophic floods along the existed hydraulic network, the physicochemical parameters of plant debris transformation during their conversion to coal, as well as the sorption properties of inclusions and interlayer of bitumen and humic acids in coal beds. An experimental technological complex was created to study the microelements transfer process in the dust-gas stream and the distribution of rare earth and trace elements separately in varieties of coal combustion products (slag, fly ash, dustlike part of the dust-gas flow, and technogenic cleaning water). The resulting combustion products of coal have been studied by inductively coupled plasma (ICP)-spectrometry methods (ICPmass spectrometry and ICP-atomic emission spectroscopy). Sample preparation technique for analysis was improved to determine the elemental composition. It was established that more than 60% of trace and rare earth elements were concentrated in ash and sludge. Data on these

“…Our previous studies dealt with the distribution of gold in coal-bearing deposits of the Zeya-Bureya basin and mountain massifs [15][16][17][18]. In the Late Cretaceous and Paleogene, gold deposits were subjected to intense weathering processes and served as sources of gold and other ore components for coal-bearing deposits.…”

Gold-Bearing Brown Coal Deposits of the Zeya–Bureya Sedimentary Basin (East Russia): Fundamental Model of Formation

The primary sources and the conditions for the formation of the Paleogene–Neogene coal-bearing deposits in the Zeya–Bureya sedimentary basin were identified and studied with the help of paleogeographic reconstructions and geochemical analyses. Based on the results obtained, we suggest a new basic model of element transfer into the coal, involving two mutually complementary processes to account for the introduction and concentration of gold and other trace elements in the sequences investigated. The first process reflects the system in which peatlands were concentrated along the basin’s junction zone and the passive internal residual mountain ranges. The second reflects the junction’s contrast-type (sharp-type) forms conditions along the external mobile mountain-fold frame. The eroded gold particles were transported over 10–20 km as complex compounds, colloids, dispersed particles, and nanoparticles, and remobilized into clastogenic and dissolved forms along the first few kilometers. The release of gold in the primary sources occurred due to weathering of gold-bearing ore zones, followed by transportation of gold by minor rivers to the areas of peat accumulation. This study considered the probability of the accumulation of high concentrations of gold and rare earth elements (REE) in coal due to the introduction of organic and inorganic materials during floods, with episodes of catastrophic events, and volcano–hydrothermal activities.
