Journal of Petroleum Geology, EarlyView.ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

Meteoritics &Planetary Science, EarlyView.Abstract A substantial fraction of organic carbon in carbonaceous chondrites has long been described as “missing,” reflecting incomplete recovery and limited resolution of operationally defined organic components. Here, we present a quantitative reassessment of the carbon budget in the Murchison meteorite using an integrated extraction–recovery mass ...

The Depositional Record, 2020 Clay minerals in fine‐grained marine sedimentary successions are most commonly considered to be detrital in origin and have been used extensively by geologists as indicators of palaeoclimate conditions in the hinterland.

Terra Nova, EarlyView.ABSTRACT Significant porosity of more than 5% was found at depths of more than 8500 m in poorly sorted, calcareous mudstones of the Malmian Mikulov Formation. These overpressured rocks are the main hydrocarbon source rock in the Vienna Basin. Core samples from present‐day depths of 8150 m to 8550 m were analysed using X‐ray diffraction and scanning ...

The Clay Minerals in the Soils of the Gypseous Belt of Barbastro, NE Spain
LandThis article examines the clay mineralogy of twelve representative soils developed from gypsum-rich parent materials on several geomorphic positions. These soils were classified as Haploxerept, plus one profile as Humixerept and another as Xerorthent ...

Application effect of smectite in livestock and poultry diets
Siliao yanjiu, 2021 Smectite is a kind of layered clay composed of extremely fine aluminosilicates. It has multiple bio-functions, such as adsorbing of mycotoxins, heavy metals, pathogenic bacteria, and bacteriotoxins, repairing and protecting the digestive gastrointestinal

Geophysical Research Letters, 2023 The frontal part of the Japan Trench plate‐boundary fault is enriched in low‐strength smectite, and this material characteristic is thought to be a factor for the large fault slip during the 2011 Mw 9.0 Tohoku‐oki earthquake.

Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy
Land Degradation &Development, Volume 37, Issue 13, Page 9084-9097, 15 August 2026.ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,
