Understanding the paleomires of Eocene lignites of Kachchh Basin, Gujarat (Western India): petrological implications

open access: yesInternational Journal of Coal Science & Technology, 2017
The present paper entails the results of the investigations carried out on the lignite deposits of Kachchh Basin. The lignite samples were drawn from five lignite seams from Panandhro lignite field (Seam-I to -V) and eight lignite seams (Seam-I to -VIII)

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Effect of hydrothermal treatment on the carbon structure of Inner Mongolia lignite

open access: yesInternational Journal of Coal Science & Technology, 2020
Understanding the structural properties of lignite during hydrothermal treatment would aid in predicting the subsequent behavior of coal during the pyrolysis, liquefaction, and gasification processes.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

open access: yesBoreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Thinking and Talking About War: How the Public in Six Countries Discusses the Outbreak of the War in Ukraine

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract The Russian aggression in Ukraine, launched on 24 February 2022, marked the return of conventional war in the European continent. While Western leaders have framed the ongoing conflict through a common narrative when speaking internationally, which varies in its national nuances, much less is known about the images and lenses that the European

Analysis of the difference between weathered coal and lignite in the conversion of biomethane

open access: yesMeitan kexue jishu
In order to find out the internal reasons for the difference in biological methane production between weathered coal and lignite, weathered coal and lignite were selected respectively, and the enriched and domesticated bacterial liquid was used as the ...

Climate Change, Demand Uncertainty, and Firms' Investments: Evidence from Planned Power Plants

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT How does demand uncertainty affect firms' investment decisions? We examine this question in the context of electricity‐producing firms' planned investments in new power plants. We measure uncertainty about future electricity demand using plausibly exogenous variation in temperature projections across scientific climate models. The results show

Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Interaction and Kinetics Study of the Co-Gasification of High-solid Anaerobic Digestate and Lignite

open access: yesMolecules, 2020
This study aims at investigating the interaction and kinetics behavior of the co-gasification of digestate and lignite. The co-pyrolysis performances of digestate and lignite blended by dry process were better than that blended by wet process, while the ...
