Extreme lithium fractionation is observed when primary minerals in andesite are transformed to secondary clay minerals and then to oxides with intensive chemical weathering in a tropical climate.
Studies since 2018 have provided competing explanations of bright radar reflections from the base of the south polar ice cap.
Faults containing clays are often considered as barriers to fluid flow but new work shows that fault processes leading to the formation of clays can increase permeability relative to the host rock.
Soil clay content is an important characteristic that affects many hydraulic and mechanical properties of soil; clay mineral type is important for their prediction.
Using beryllium isotopes to track in situ formation of clays in the ocean, known as reverse weathering, will improve global models of atmospheric carbon dioxide and ocean alkalinity.
An ancient folk remedy, blue-green iron-rich clay, kills antibiotic-resistant bacteria using a one-two punch, a new study shows.
Cosmogenic silicon-based estimates of the amount of biogenic silica stored in clays along continental margins could explain the large discrepancy in the nutrient’s global marine budget.
A new model shows that the Intertropical Convergence Zone wasn't always a single band around the equator, which had drastic effects on climate.
During the Ediacaran period more than a half billion years ago, clay mineral coats likely shielded delicate remains, helping them become exquisitely preserved in rock, recent experiments suggest.
