Inorganic geochemistry and petroleum source evaluation of organic black shale in the Mamfe Basin (West Africa)

Solid Earth Sciences, 2019
The shales of the Mamfe basin, West Africa, were studied using inorganic geochemical analysis to investigate the origin of the organic matter, environment of its deposition, paleoproductivity and organic matter preservation, organic matter maturity and ...

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

Boreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

The marine conservation deposits of Monte San Giorgio (Switzerland, Italy): the prototype of Triassic black shale Lagerstätten

Swiss Journal of Palaeontology
Marine conservation deposits (‘Konservat-Lagerstätten’) are characterized by their mode of fossil preservation, faunal composition and sedimentary facies. Here, we review these characteristics with respect to the famous conservation deposit of the Besano

Lithofacies palaeogeography, depositional model and shale gas potential evaluation in the O3-S1 Wufeng-Longmaxi Formation in the Sichuan Basin, China

China Geology
: The black shales of Wufeng and Longmaxi Formation (Late Ordovician-Early Silurian period) in Sichuan Basin are the main strata for marine shale gas exploration, which have a yearly shale gas production of 228×108 m3 and cumulative shale gas production ...

Inflation expectations and time variations in the oil price pass‐through

Economic Inquiry, EarlyView.
Abstract Previous literature suggests that the pass‐through of oil price shocks to inflation rates became weaker since the 1970s. I use a time‐varying parameter VAR to show that this trend has recently been reversed with headline and core inflation rates responding more sensitive to oil price shocks. Based on a counterfactual analysis, I offer evidence

Organic petrology and geochemistry of the Upper Ordovician-Lower Silurian Renheqiao Formation shales of the Baoshan Block, western Yunnan, China

International Journal of Coal Science & Technology
Lower Paleozoic black shales are important source rocks worldwide. The Upper Ordovician-Lower Silurian Renheqiao Formation of the Baoshan Block is a low-maturity equivalent of the Wufeng-Longmaxi (WF-LMX) Shale of the Sichuan Basin.

Uranium and Rare-Earth Elements in Dictyonema Shale of the Baltic Sedimentary Basin (Kaibolovo-Gostilitsy Area)

Georesursy
The article presents the results of the study of dictyonema shales of the Baltic basin (Leningrad Oblast, Kaibolovo-Gostilitsy prospecting area) for uranium (updated data on uranium mineralization of dictyonema shales) and rare earth elements (for the ...

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

Journal of Anatomy, EarlyView.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Mechanisms of Uranium and Thorium Accumulation in the Lower Ediacaran Marine Sediments from the Upper Yangtze Platform, China: Implications for Helium Exploration

Journal of Marine Science and Engineering
The ocean is a significant global reservoir of uranium (U) and thorium (Th). These elements can be incorporated into marine sediments through processes involving organic matter (OM), redox conditions, terrigenous inputs, and mineral interactions.
