Spatial and temporal evolution of a coastal erg margin: the Middle Jurassic Page Sandstone, southern Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Aeolian deflationary events are erosive to static stages where sediment supply is insufficient to support bedform migration and preservation in the rock record. In the vicinity of shallow‐marine environments, inland rises of relative water table and associated generation of deflationary super surfaces may be driven by the onset of ...

Genesis of Soils from Bauxite in Southeastern Brazil: Resilication as a Soil-Forming Process

open access: yesRevista Brasileira de Ciência do Solo, 2017
Pedological studies using X-ray diffraction (XRD), X-ray fluorescence (XRF), optical microscopy, and scanning electron microscopy (SEM-EDS) showed a Xanthic Ferralsol formed from the degradation of bauxite on a slope in the Caparaó region, in ...

Changes in soil test phosphorus are not predictable using fertilizer input and crop removal

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Volatile fertilizer prices have led to many producers and researchers exploring different immobile nutrient stratagems to increase the efficiency of fertilizer applications, leading to greater economic return. While many nutrient recommendations are based upon a soil test for that one season, for immobile nutrients such as phosphorus (P ...

Magnetic Difference Between Deep and Surface Soil Within an Agricultural Area in Southern China: Implications for Magnetic Mineral Transformation During Pedogenic Process Under Subtropical Climate

open access: yesEarth and Space Science, 2020
Mineral magnetism is proved as a sensitive method of pedogenesis by numerous studies. However, formation pathways of magnetic minerals and subsequent magnetic response are quite different under different climate.

Loess Studies in Aotearoa New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Calcium and Multi‐Isotope Constraints on Cation Exchange in Groundwater

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
Abstract Cation exchange is one of the most important processes in water‐rock interaction in the presence of clay minerals, with a common Ca‐Mg‐Na exchange system. However, systematic verification of Ca isotopes for tracing cation exchange in natural environments is lacking due to overlapping factors, such as dissolution‐precipitation of Ca‐minerals ...

Stratified Pit Features at the Presbytère de l'Ancienne‐Lorette (CeEu‐11) and the Fort Odanak (CaFe‐7) Sites in Québec, Canada: A Comparative Geoarchaeological Analysis

open access: yesGeoarchaeology, Volume 41, Issue 3, May/June 2026.
ABSTRACT A geoarcheological study of two large, stratified Indigenous pit features discovered at two Jesuit mission sites in Québec (Canada) was carried out to offer a detailed documentation of their contents and better understand their use over time. One of the pits is a 17th c.
