Two soil profiles developed from mafic saprolites were examined at Economy Mountain, Nova Scotia and Kamloops, British Colombia. The underlying rocks, a tholeiitic basalt in Nova Scotia and a basic greenstone schist at Kamloops, were apparently transformed to predominantly smectitic saprolites in pre-Holocene times. During the Wisconsinan glacial stage the sola and a significant portion of the saprolites were removed. Holocene pedogenesis has produced new sola on the saprolites. In Nova Scotia, the solum may have some locally derived till or colluvium component. Key words: Mafic pedogenesis, Paleosols, soil mineralogy
