WebIf we assume the dependence of the lithospheric thickness on its age in the form h(t)=6·6t1/2+7·5, then this model can roughly approximate the measured heat flow. In this model the horizontal conductive term is not negligible, the heat flow depends both on time and on the velocity of the sea-floor spreading which should be taken into account for the …
