About the heat flow from the Earth’s interior

Abstract

Abstract The main objective of this work is to show how values of heat loss from the Earth’ interior can be obtained. There are two kinds of data necessary for this calculation: heat flow at the surface and geological data. We present these data as they appear in recent works. Because the distribution of heat flow data-points is inhomogeneous, it is necessary to make estimations in some regions and to use average values in other. We then discuss methods used to compute heat flow in continents, including the method used by Jaupart et al (2007) which questions the relationship between heat flow and the age of continents presented by Polyak and Smirnov (1968). We than present models used to obtain heat flow in oceans. The estimated values of heat loss range between (29 -34) TW and (47±2) TW.
