Mantle convection is important in understanding the heat flow and thermal structure of the continental lithosphere, as it produces time variability in the surface heat flow, and allows for lateral advection of heat under a continent. Many of the fundamental questions in continental heat flow depend on the magnitude and variability of the mantle contribution to continental heat flow. We summarise the current understanding of the thermal state of the Australian continent, and discuss the application of mantle-convection modelling results to continental heat-flow problems. A particle-in-cell finite-element code is used to show how the continental thermal field is modulated through...
