A detailed paleomagnetic and rock-magnetic investigation of the Matuyama-Bruhnes geomagnetic reversal recorded in tephra-paleosol sequence of Tlaxcala(Central Mexico)

Frontiers in Earth Science, 2015
Geomagnetic reversals are global phenomena, for about 50 years the paleomagnetists attempted to acquire as many detailed records as possible using the magnetic memory of sediments and lava flows.

Shale Tectonics in the Hyperextended Continental Margin of the Niger Delta

Tectonics, 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.

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

Basin 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

Permafrost 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.

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

Journal 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 ...
