Late Quaternary paleosols, stratigraphy and landscape evolution in the Northern Pampa, Argentina [PDF]

, 2006
The field properties, micromorphology, grain-size, geochemistry, and optically stimulated luminescence (OSL) ages of two late Quaternary sections have been used to reconstruct the sequence of pedosedimentary processes and to provide insights into ...

Springtime Formation of Laminated Soil Carbonate Rinds and Changes in Fluvial Terrace Soils on Orbital Timescales at Rio Mesa, Utah, USA

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Laminated soil carbonate rinds are a Quaternary paleoclimate archive whose isotope composition is linked to soil formation conditions. At Rio Mesa, Utah (USA), we investigated the fidelity of rind records in a river terrace setting by determining the seasonal timing of rind formation and testing for inter‐record replication.

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

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)

Comparison of the Late Miocene Sediments and Early Quaternary Red Paleosols in the Penghu Islands, Taiwan and Zhangpu, Fujian

, 2023
This study aims to compare the clay mineralogy and whole-soil major chemistry of elements in late Miocene soil sediments and early Quaternary red paleosols in the Penghu Islands, (Pescadores), Taiwan, and Zhangpu Volcanic Park, Fujian.

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.
