An Aeolian Depositional Sequence Shaped by Near‐Surface Water at the Base of the Layered Sulfate Unit, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The basal strata of the orbitally defined Layered Sulfate unit (LSu) in Gale crater, Mars, marks the end of a major mineralogical transition from clay‐to sulfate‐bearing stratigraphy. This has previously been attributed to a period of significant aridification of Gale's climate. Here, we present ground‐based observations by the Curiosity rover

Relief in Aeolian Environment. The Surface of Nida Settlement

Archaeologia Lituana, 2019
During archaeological investigations in Nida settlement in 1974–1978, 2011–2013 and 2016 a lot of stratigraphic data from considerably wide area was gathered.

ENSO‐Mediated Linkage Between the East Asian Summer Monsoon and Cordilleran Ice Sheet Discharge During MIS 3

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)

Geochemical Disequilibrium at the Brittle‐Ductile Transition

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

Weathering of the Emeishan Large Igneous Province Enhanced the Nutrient Flux to the Oceans and Led to Late Permian Climate Cooling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract Mafic continental large igneous provinces (LIPs) erupted rapidly and may have overwhelmed Earth's atmospheric and biospheric systems. However, the exact balance and interplay between short‐term climate warming caused by CO2 emissions and long‐term cooling due to LIP weathering remains poorly understood.

Quaternary pedostratigraphy of the Nevado de Toluca volcano

Revista Mexicana de Ciencias Geológicas, 2018
Paleosol sequences of the Nevado de Toluca volcano (NTV) preserve a detailed record of late Quaternary environmental change. In fact, some studies have been used the NTV paleosols to interpret paleoenvironmental conditions, however some uncertainties ...

The Difference in Shear Behavior and Strength between Loess and Paleosol and Their Prediction of Unsaturated Strength

Applied Sciences
In recent decades, loess landslide events have attracted increasing attention in the South Jingyang tableland. To elucidate the mechanical mechanism of landslide initiation in the region, this work collected undisturbed loess and paleosol samples taking ...

Calcium Nodules as a Proxy for Quaternary Paleoclimate Change on China's Loess Plateau. [PDF]

PLoS ONE, 2015
Different proxies have been used to investigate Quaternary paleoclimate change. Here, we used weathering of calcium nodules in paleosols on China's Loess Plateau as a proxy for Quaternary paleoclimate changes to provide an alternative indicator of these ...
