Iron Isotopes Reveal Fe Export Driven by Change of Tropical Weathering Regime

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Unraveling paleoenvironmental signals recorded in laterites is crucial for quantifying weathering‐driven elemental fluxes at the Earth's surface. New stable iron isotope data (δ56Fe), combined with (U‐Th)/He ages in Fe‐oxides from a ferruginous duricrust from French Guiana, reveal the response of Fe hosted in laterite to past changes in ...
