Potential Unconventional Gas Plays in Mature Basin of the Czech Republic [PDF]

, 2016
The presence of unconventional resources has been proven in deeper parts of mature oil and gas provinces and coal basins of the world. In this context, it is worth to focus also on the prospects of unconventional gas production from within hydrocarbon ...

Terrestrial Ecosystem Response to Changing Temperature and Seasonality in the Paleocene‐Eocene Thermal Maximum: Shallow Marine Records From the Salisbury Embayment, USA

Paleoceanography and Paleoclimatology, Volume 41, Issue 3, March 2026.
Abstract The Paleocene‐Eocene thermal maximum (PETM, ∼56 Ma) is marked by a massive and rapid rise in atmospheric CO2 and ∼5°C of global warming. It is globally characterized by a negative carbon isotope excursion (CIE), and, at least locally, is preceded by a pre‐onset excursion (POE).

Palaeoenvironments and palaeoceanography changes across the Jurassic/Cretaceous boundary in the Arctic realm: case study of the Nordvik section (north Siberia, Russia) [PDF]

, 2014
The Jurassic/Cretaceous transition was accompanied by significant changes in palaeoceanography and palaeoenvironments in the Tethyan Realm, but outside the Tethys such data are very scarce.

The Carboniferous-Permian transition in Arunachal Pradesh, North East India: A palynological and palynofacies study

Earth History and Biodiversity
Palynological and palynofacies analyses were carried out from an outcrop of the Bichom Formation located in Arunachal Pradesh, North-East India. The age of the Bichom Formation at this locality is inferred based on palynological investigation and ...

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Mechanism of Late Campanian–Early Maastrichtian oil shale deposition and its sequence stratigraphy implications inferred from the palynological and geochemical analysis

Egyptian Journal of Petroleum, 2014
Understanding the organic rich sediment deposition mechanism is vital for the purposes of their exploration. This should reconsider the sequence stratigraphic framework and its associated paleoenvironmental setting.

Unusual biota and palynofacies of a Lower Devonian intermontane basin saline lake–playa mudflat ecosystem

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Strathpeffer–Struie Lower Devonian LORS (Lower Old Red Sandstone) deposits of the Northern Highlands of Scotland contain the decidedly unusual ‘foetid beds’. These are interpreted as being deposited in a highly saline sulphate lake and associated playa mudflat, which developed in an intermontane basin in the Caledonian Mountains of ...
