Evolution of Iapetus according to our hypothesis: A—homogeneous satellite after accretion. B—high density core enclosed by the ice layer as a result of melting, gravitational differentiation and freezing. The ice thickness is latitude dependent as a result of inertial forces. C—gravitational overturn by axially symmetric flow. D—present structure of Iapetus.
