Soil development and ancient Maya land use in the tropical karst landscape: Case of Busiljá, Chiapas, México

Soil Science Society of America Journal, Volume 88, Issue 5, Page 1561-1582, September/October 2024.
Abstract The soil mantle of the tropical karstic landscapes of Southern Mexico was shaped by specific processes of pedogenesis and long‐term human impacts of ancient Maya agriculture. To understand the interaction between natural and human‐induced soil‐forming processes in the calcareous mountains of Chiapas state, we studied soil toposequences around ...

Unveiling the Transition From Paleolake Lisan to Dead Sea Through the Analysis of Lake Paleoshorelines and Radiometric Dating of Fossil Stromatolites

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 8, August 2024.
Abstract To date, the most complete paleolake‐level reconstructions for the late Pleistocene water bodies that once occupied the Dead Sea depression have been based on the combination of dating of lake sediments and terrestrial materials. However, despite these major accomplishments, there is still limited spatial control regarding the water levels ...

Slab Driven Quaternary Rock‐Uplift and Topographic Evolution in the Northern‐Central Apennines From Linear Inversion of the Drainage System

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 7, July 2024.
Abstract Investigating rock‐uplift variations in time and space provides insights into the processes driving mountain‐belt evolution. The Apennine Mountains of Italy underwent substantial Quaternary rock uplift that shaped the present‐day topography. Here, we present linear river‐profile inversions for 28 catchments draining the eastern flank of the ...

Analysis and Characterization of Paleosoil: A Preliminary Study and Possible Applications in Forensic Archaeology [PDF]

International Journal of Archaeology, 2015
This paper presents the results of analysis conducted on soil samples collected on the Isola delle Statue in Porto Marghera (Venice, Italy). The analyses were aimed at the mineralogical – petrographic characterization and evaluation of the possible presence of layers of a paleo soil (Neolithic age).

Radiocarbon dates from the Netherlands and Doggerland as a proxy for vegetation and faunal biomass between 55 and 5 ka cal bp

Journal of Quaternary Science, Volume 39, Issue 2, Page 248-260, February 2024.
ABSTRACT Three hundred forty‐one radiocarbon dates from the Groningen radiocarbon database are compiled in this study. They show for the first time that organic sediment samples from the eastern Netherlands and mammal bones from Doggerland reflect shifts in the presence and the density of vegetation (food for herbivores) and mammal biomass during the ...

Joint application of fluid inclusion and clumped isotope (∆47) thermometry unravels the complexity of thermal and fluid‐flow history reconstruction in sedimentary basins—Upper Triassic Chaunoy Formation reservoirs (Paris Basin)

Basin Research, Volume 36, Issue 1, January–February 2024.
Precipitation timing and δ18Ofluid for the studied diagenetic carbonates obtained from different temperature datasets (fluid inclusions, ∆47). Abstract We investigated calcites and dolomites precipitated during burial diagenesis of the Upper Triassic (Norian) continental siliciclastics from sub‐surface reservoirs of the northern Paris Basin (Chaunoy ...
