Identifying Temperature and Moisture Controls on Fe Oxide Origins
Geophysical Research Letters, 2023 Magnetism, redness, and Fe oxides are indicators of pedoclimatic conditions. However, uncertainties with observing how Fe oxides form within soils has led to debates about relationships between magnetic mineral assemblages, temperature, and rainfall.
