The geosynclinal mountain and continent building cycle according to the ^vriter (Dietz, 1963). This actualistic concept suggests that prisms of sediment under the continental rise at the base of the continental slope collapse by sea-floor thrusting to form folded mountains of graywacke or flysch lithofacies. By this interpretation the mobility ob- served in eugeosynclinal mountains indicates activity of the sea floor rather than collapse of the continental sialic plate. The sea floor is active, and the continent is passive. This is in contrast to the tectogene hypothesis or to the island arc-tectonic borderland view (Kay, 1951). By the writer's concept, the terms continent and craton become essentially equivalent. (From Dietz and Holden, in press.).
