A theory of two-dimensional geothermic problems is elaborated by the active temperature function at the vertical contact of two horizontally layered media. The approach offered before for oceanic ridges is extended to the case of continental margins

A majority of recent data on heat flow observations on the world-wide rift system is from the oceanic ridges. The main feature of these distributions is the presence of a peak in the heat-flow distribution for profiles crossing these structures. The

A heat flow pattern in the Baikal rift zone is obtained, and a form of maximum of heat flow under the Baikal rift valley is revealed. Calculations have shown that the heat flow anomaly under the Baikal rift zone cannot be related to the surface facto

An effect of melting on the thermal history of the Earth is considered in a numerical experiment, the basis of which is an inhomogeneous quasilinear equation of heat conductivity. This implies the introduction of two new ideas into the computation pr

Analysis of heat flow measurements on the sea bottom and in deep water areas inside the USSR has made it possible to correlate the regional thermal anomalies with different tectonic structures. A high heat flow was observed in the Baikal Lake rift zo
