Tectonics, Volume 42, Issue 6, June 2023., 2023 Abstract The Trans‐Mexican Volcanic Belt is an active continental volcanic arc related to subduction along the Middle America trench. It is characterized by intra‐arc extension resulting into several major arc‐parallel active fault systems and tectonic basins.

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 6, June 2023., 2023 Abstract The Okavango Delta in North Botswana is a hot‐spot of biodiversity within the semi‐arid central part of the South African plateau. This endorheic ecosystem is highly dependent on the annual flood that brings freshwater from the highlands of Angola to the North.

SOIL ORGANIC CARBON DATING OF PALEOSOILS OF ALLUVIAL FANS IN A BLOWN SAND AREA (NYÍRSÉG, HUNGARY) [PDF]
Radiocarbon, 2022 ABSTRACTThe most widely used dating techniques in quaternary research are the radiocarbon (14C) and optically stimulated luminescence (OSL) dating methods. In some environments, the investigated sediments do not contain enough material for14C dating. In these cases,14C dating of bulk sediment may be used as a last resort.

Global Biogeochemical Cycles, Volume 37, Issue 1, January 2023., 2023 Abstract In organic soils, the availability of terminal electron acceptors (TEAs) determines the ratio of CO2 to CH4 formation under anoxic conditions. While the importance of electron accepting capacities (EACs) of organic matter is increasingly acknowledged, redox properties of organic matter have only been investigated in a limited set of peat and ...

Active Back‐Arc Thrust in North West Java, Indonesia
Tectonics, Volume 41, Issue 7, July 2022., 2022 Abstract The Java Back‐arc Thrust scars the entire back‐arc area of Java Island, but the faults' nature, timing, and activity remain partly elusive. Characterizing the structure and activity of the seismogenic Java Back‐arc Thrust (historical earthquakes up to 7 Mw) is a cornerstone to evaluate associated geohazards.

Multi vegetation model evaluation of the Green Sahara climate regime
Geophysical Research Letters, 2017 During the Quaternary, the Sahara desert was periodically colonized by vegetation, likely because of orbitally induced rainfall increases. However, the estimated hydrological change is not reproduced in climate model simulations, undermining confidence ...

Studia Universitatis Babeș-Bolyai Ambientum, 2021 Optically stimulated luminescence dating is widely used for establishing high-resolution chronologies for the Quaternary in paleoclimate research. Loess is an important archive of past climate changes on continents. In order to provide a first absolute chronology for Zemun loess paleosol sequence in Serbia, the single-aliquot-regenerative dose (SAR ...
