Studies of recent years, notably from metamorphic terrains, have resolved the magnitude and direction of apparent polar wandering (APW) motions over much of Proterozoic times. This paper re-examines the case for a Proterozoic supercontinent, and shows that both the polarities and the positions of the Proterozoic paleopoles from the major shields conform to a single APW path using a unique reconstruction. These data imply that the continental crust was amassed together as a single lens-shaped body as heat loss by extensive small-scale mantle convection correlating with low rates of APW was replaced by a large-scale mantle convection system responsible for...
