Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...

Conditions and timing for the precipitation of early marine diagenetic dolomite in the Triassic Dolomia Principale (northern Italy)

Sedimentology, EarlyView.
ABSTRACT Thermodynamic constraints and empirical evidence often suggest that fabric‐retentive replacement dolomites are stable carbonate minerals that preserve ancient seawater properties. This study evaluates this hypothesis by examining the Upper Triassic Dolomia Principale in Northern Italy.

Foliar Biofortification of Lentil (Lens culinaris Medik.) With Iron, Zinc, and Selenium: Multi‐Environment Evaluation in Bangladesh

Legume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Micronutrient malnutrition remains a major global challenge, particularly in developing countries of South Asia, where diets are dominated by cereal‐based foods with low mineral content. Lentil is a nutrient‐rich legume with strong potential for biofortification to enhance dietary intake of iron (Fe), zinc (Zn), and selenium (Se).
