Abstract

Deep weathering profiles result largely from hydrolysis of silicate minerals below the water table. Unless water is frozen, surface temperatures do not affect the depths at which changes occur, and groundwater may be present despite dry surface climate. Deep weathering is therefore largely independent of surface climate. Independent geological evidence shows that much deep weathering occurred in the Mesozoic and early Cenozoic when climates were warm and wet, but deep weathering and kaolin formation can also occur in cold climates
