Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta

open access: yesTectonics, Volume 44, Issue 7, July 2025.
Abstract Based on the interpretation of a large seismic data set, we provide a comprehensive description of the structures affecting the entire Niger Delta, from the onshore domain to the deep‐offshore. The shale‐dominated delta lies on a divergent segment of the west African passive margin.

Natural environments of period of the formation of Dubno paleosoil in Halych-Dniester region

open access: yesVisnyk of the Lviv University. Series Geography, 2011
In the article have been suggested the analysis of main lithology-petrography characteristics of Dubno paleosoil complex in Halych-Dniester region. The natural environments of period of the formation of paleosoil have been reconstructed, based on mollusc fauna analysis.

Revisiting the Stratigraphy and Structure of the Faroe Islands Flood Basalts for Large‐Scale CO2 Storage in Basalt Reservoirs

open access: yesBasin Research, Volume 37, Issue 3, May/June 2025.
Storing CO2 in volcanic rocks has lately shown promising results; however, volcanic provinces are highly heterogeneous, implying challenges in mapping and exploring for potential CO2 reservoirs. This study showcases the importance of integrating a variety of data types across all scales in a case study in the Faroe Islands Basalt Group, North Atlantic ...

Greenhouse Gas Production and Microbial Response During the Transition From Terrestrial Permafrost to a Marine Environment

open access: yesPermafrost and Periglacial Processes, Volume 36, Issue 1, Page 63-82, January/March 2025.
ABSTRACT Arctic permafrost coasts, affected by rising sea levels and increasing coastal erosion in a warming climate, undergo significant changes. Simulating how permafrost is impacted by inundation with fresh, brackish and marine water enhances our understanding of permafrost carbon stock responses to increasingly marine conditions.

Secondary carbonates in loess-paleosoil sequences: a general review

open access: yesOpen Geosciences, 2011
Abstract The literature dealing with secondary carbonates in loess-paleosoil sequences is in many cases ambiguous, which means that different concepts are used for the same features, whereas certain concepts referring to different types are used as collective nouns.

Glacial Erosion Rates Since the Last Glacial Maximum for the Former Argentino Glacier and Present‐Day Upsala Glacier, Patagonia

open access: yesJournal of Geophysical Research: Earth Surface, Volume 129, Issue 12, December 2024.
Abstract Recovering the patterns of glacial erosion over time is key to understanding feedbacks between climate and tectonic processes. Glacial erosion rates have been shown to systematically increase worldwide toward the present since the late Cenozoic, a behavior interpreted as the response of glaciers to a cooling and increasingly variable climate ...

Age, composition and spatial distribution of sandy loess in north‐eastern Germany (Fläming, Brandenburg)

open access: yesEarth Surface Processes and Landforms, Volume 49, Issue 11, Page 3261-3282, 15 September 2024.
Sandy loess deposits in the Fläming ridge (Brandenburg, Germany) were analysed with respect to their composition, depositional age and distribution in the landscape. They most likely originate in the lowlands to the north and were deposited during the late MIS 2 (19–14 ka), in analogy to loess deposits found further west and south.
