A preliminary analysis of convection in a mantle with a heterogeneous distribution of heat-producing elements

, : A preliminary analysis of convection in a mantle with a heterogeneous distribution of heat-producing elements. Physics of the Earth and Planetary Interiors 34(1-2): 68-76

Distribution of elements is changed by the convective motion. Depending on the types of the element distribution, there may occur, (1) oscillation of convective motion, (2) decrease of the amplitude of convection, and (3) conservation of the original distribution of heat-producing elements for a considerable length of time. These results imply that heterogeneity and convective motions in the mantle may have a close connection with each other.
