Coal has formed in terrestrial and coastal-marine environments from sub-polar to equatorial regions since the Devonian. It contains detailed long-term records of contemporaneous environment, climate, subsequent modifications. However, general, direct chronological information coal been sparse. The investigated present study is Mile intermontane basin, Yunnan Province, China, north an arm Mesozoic Tethys Ocean. marine geochemical signatures syngenetic gypsum, common sediments. gypsum...
Igneous intrusions can bring hydrothermal fluids, metals, and ligands to the surrounding host sequences, changing their physical, textural chemical features some extent depending on degree of thermal exposure. However, regarding hydrothermally-altered coals, previous studies have predominately focused variations in coal quality, chemistry mineralogy, despite growing research stable radioactive isotopes within coal-bearing sequences. The Pennsylvanian from Daqingshan Coalfield, Inner...
The soil microbiome plays an important role in wetland ecosystem services and functions. However, the impact of hydrological conditions on microorganisms is not well understood. This study investigated effects wetted state (WS); wetting–drying (WDS); dried (DS) diversity bacteria, fungi, archaea. Shannon index bacterial was significantly different various flooding (p > 0.05), however, fungal archaeal communities were < 0.05). Significant differences found beta bacterial, fungal,...
This study presents recently collected data examining the organic petrology, palynology, mineralogy and geochemistry of Gray Hawk coal bed. From Early Pennsylvanian, Langsettian substage, has been mined near western edge eastern Kentucky portion Central Appalachian coalfield. While is thin, rarely more than 0.5-m thick, it a low-ash yield low-S content, making an important local resource. The palynology dominated by Lycospora spp., contains diverse spectrum small lycopods, tree ferns,...
Abundances, modes of occurrence, enrichment, and origin critical elements in coal coal-bearing sequences have attracted much attention recent years. Previous investigations attributed REE-Y-Nb-Ta-Zr-Hf mineralization coals intra- inter-seam tuffs to alkali volcanic ash eruptions subsequent hydrothermal alteration. In this study, two major minable seams (D101 W407) that are located the lowermost uppermost Wuchiapingian Longtan Formation Liupanshui Coalfield, Guizhou, southwestern China, were...
Terrigenous materials from sediment-source regions are important controls on the types and concentrations of inorganic components in coal. The Kangdian Upland (dominated by Emeishan basalts) is dominant terrigenous supplier for most Late Permian coals, as well their associated host rocks (roof floor strata) southwestern China. high volatile bituminous coals (Nos. 3 6 coals) two major minable coal seams Tucheng deposit Unlike this region that characterized elevated element assemblage...
Determination of the geochemical and mineralogical characteristics coal can provide useful information on geological setting evolution basins assist in identifying factors that control distribution minerals elements interest. The Late Permian coals southwestern China have received much attention because some these are usually considered to be potential sources critical metals high concentrations potentially toxic elements. Mineralogical analyses were carried-out from Kulishu Sijichun mines...
Two carbon centered amino radical (CH2NH2 and CH3CHNH2) reactions with O2 were scrutinized by means of laboratory gas kinetics experiments together quantum chemical computations master equation modeling. In the experiments, laser photolysis alkylamine compounds at 193 nm was used for production photoionization mass spectrometry employed time-resolved detection reactants products. The investigations performed in a tubular, uncoated borosilicate glass flow reactor. rate coefficients obtained...
Abstract. Although anthropogenic dust has received more attention from the climate research community, its dominant role in production process is still not identified. In this study, we analysed relationship between and population density/change over global semi-arid regions found that are major source producing dust. The results showed obvious cropland than other land cover types (crop mosaics, grassland, urbanized regions) of increases as density grows to 90 persons km−2. Four selected...
Rare earth elements while not considered to be volatile in coal combustion do show some variation between ash collection rows. To better understand this variation, we investigate the trace element variations (with emphasis on rare elements) size fractions of fly from multiple rows at a single power-generating unit southeastern Kentucky power plant. Fly samples were investigated using optical microscopy, X-ray fluorescence, and inductively coupled plasma mass spectrometry. The arsenic...
The coal-hosted Ge deposit (Early Cretaceous) at Wulantuga, Inner Mongolia, northern China, is one of the largest deposits in world. Although origin, modes occurrence, and spatial distribution this have been investigated by several studies, provenance pathways from source to are largely unknown. In study, we 87Sr/86Sr values high-Ge coal Wulantuga stratigraphically-equivalent low-Ge No. 1 Pit, both Shengli Coalfield, China. addition an organic association, Sr Ca coals also occur gypsum....
