“…The Wyodak‐Anderson member alone contains an estimated 550 Gt economically recoverable coal in beds as much as 60 m thick [ Ellis et al , 1999]. Documented Paleocene coal fields in Russia [ Crosdale et al , 2002] and Pakistan [ Jaleel et al , 1999] tend to have somewhat thinner seams (up to 20 m) and smaller reserves (175 Gt, Thar coalfield, Pakistan) than the Wyodak example but are still significant examples of Paleocene lignite deposits.…”

“…This amounts to an average carbon release by burning of 0.7 × 10 14 moles C/y, which is within the range estimated for Indonesia in 1997, and perhaps not unreasonable given the widespread occurrence of unusually thick peatlands inferred from the Paleocene coal record. Interestingly, Crosdale et al [2002] noted that some Paleocene Russian coals are unusually rich in inertinite, and inferred that fire played an important role in Paleocene peatlands of the Zeya‐Bureya Basin. Unusually high concentrations of macroscopic charcoal have been identified in lignite beds at the Paleocene‐Eocene boundary in southern England [ Scott , 2000; Collinson , 2001; Collinson et al , 2003] suggesting that wildfire could have contributed to the observed abrupt negative carbon isotope excursion.…”

Early Cenozoic decoupling of the global carbon and sulfur cycles

et al. 2003

[1] Changes in carbon and sulfur cycling over geologic time may have caused considerable modification of atmospheric and oceanic composition and climate. Here we calculate pyrite sulfur (S py ) and organic carbon (C org ) burial rates from recently improved Cenozoic stable isotope records, and from these rates we infer global changes in C org burial environments. Given predominantly normal shelf-delta organic carbon burial, the global S py burial flux should be coupled to C org burial. However, we find that the major early Cenozoic peak in C org burial coincides with a minimum in S py burial. Although the calculated magnitude of variations in global pyrite burial flux is sensitive to our assumptions about the concentration of sulfate in paleoseawater, a non-steady-state isotope mass balance model indicates very low S py burial rates during the Paleocene and a dramatic increase starting near the Paleocene-Eocene boundary, dropping off to a fairly constant Cenozoic rate beginning in the middle Eocene. High C org /S py burial ratios (C/S mole ratio %15-30) coinciding with the Paleocene carbon isotope maximum most likely reflect enhanced accumulation of terrestrial organic carbon in Paleocene terrestrial swamps. We suggest that rapid burning of accumulated Paleocene terrestrial organic carbon could have significantly contributed to the short-lived negative carbon isotope excursion at the Paleocene-Eocene boundary in addition to or possibly even as an alternative to release of gas hydrates from the continental slopes. An early Eocene minimum in calculated C org /S py burial ratios (C/S mole ratio %2-4) suggests that the predominant locus of organic carbon burial shifted to euxinic environments in a warm early Eocene ocean.

Sandstone composition of the Upper Jurassic Emuerhe Formation from the Mohe Basin, China

et al. 2013

The sandstone composition analysis carried out on the samples from three different sections (western section, middle section and eastern section) of the Upper Jurassic Emuerhe Formation in the Mohe Basin, northeastern China, reveals that the Okhotsk orogenic belt and the Ergun massif basement are the source areas for the Emuerhe Formation. The source area of the western section and the A segment of the middle section is the Okhotsk orogenic belt. The tectonic attributes of the Okhotsk orogenic belt are those of a dissected arc. The transportation distance of clastic rocks from these sections gradually lengthened, and the uplift rate of the Okhotsk orogenic belt gradually increased. The source area of the eastern section and the B segment of the middle section is the Ergun massif basement. Compared with the Okhotsk orogenic belt, the tectonic attributes and uplift rate of the Ergun massif basement are different from the former. The attributes of the Ergun massif basement are those of basement uplift. The transportation distance of clastic rocks from the eastern section and the B segment of the middle section gradually shortened, and the uplift rate of the Ergun massif basement gradually decreased. These conclusions are consistent with the characteristics of a foreland basin. Thus, we can draw the conclusion that the Mohe Basin belongs to the foreland basin.

“…Coals of the Arkharo-Boguchanskoe and Yerkovetskoe deposits corresponded to sub-bituminous coal, and the Sergeevskoe Deposit to lignite. The burial depth of the former two was approximately 1000 m, while that of the latter was no more than 500 m [22].…”

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

et al. 2021

View full text Add to dashboard Cite

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.
