Abstract

26 new heat flow and 13 radiogenic heat production measurements from Zimbabwe, Zambia and Tanzania are reported together with details and some revisions of 18 previous heat flow measurements by other investigators from Kenya and Tanzania. These measurements come from Archean cratons, Proterozoic mobile belts, and Mesozoic and Cenozoic rifts. In comparing heat flow in east and southern Africa, a common heat flow pattern of increasing heat flow away from the centers of the Archean cratons is observed. This pattern suggests a fundamental difference in lithospheric thermal structure between the Archean cratons and the Proterozoic and early Paleozoic mobile belts which surround them. Superimposed on this common pattern are two regional variations in heat flow. -from Authors
