Cryogenic physico‐chemical precipitations: Iron, silica, calcium carbonate
Abstract In Quaternary and present‐day alluvial deposits, secondary mineral accumulations are common. Previous theoretical and experimental studies have shown the occurrence of frost‐related iron and calcium carbonate precipitations. Microscopic and ultramicroscopic observations of alluvial material...
