Reverse Weathering, Clay Mineral Formation, and Oceanic Element Cycles

Reverse weathering is a process by which new clays are formed by chemical combination of elemental material from oceans and marine sediments. Mackenzie and Kump review the history of research into this process and comment on the research report by Michalopoulos and Aller ( p. 614 ), which has “reopened the Pandora's box of reverse weathering in sediments.”
