you are: the Analysis of a superficial thermal stream

The described method was used for studying of possible influence lateralnyh neodnorodnostej heat sources on temperature distribution on depth in earth crust and the top cloak along a profile stretched from Corsica to Leningrad.

Local features of a thermal field of this profile for calculations of value represented here have no. Therefore the surface temperature is accepted by a constant (0 °s), and values of a thermal stream act in film from a card of a thermal stream of Europe approximated by a surface of a trend of 6th order. For calculations of distribution of temperature on depth the three-layer model is used: a layer 1 - earth crust to depth of 30 km, a layer 2 - the top horizons of a cloak (30-100 km), a layer 3 - the bottom part of the top cloak (100-700 km).

In each layer it is supposed lateralnaja variability of generation of heat within the set interval.

According to materials of several authors about a thermal stream qm on bark and cloak border 60% of the general thermal stream observed at a terrestrial surface were supposed, that, is generated by the sources of heat located in a bark.

In a layer 1 (earth crust) are supposed lateralnye variations of allocation of heat in a range of 1-5 units of generation of heat (HGU) according to the data resulted by various authors. The values of a thermal stream calculated on optimised model of sources, are very close to an observable thermal stream. It is necessary to underline, that temperature anomalies in this case extend to depths of an order of 500 km.

In a layer 2 change of size of generation of heat in limits from 0,1 to 1,0 HGU is supposed. The thermal stream received on this optimised model, badly coincides with nabljudennymi values. In case of 3, where are supposed lateralnye variations of sources of heat in a layer 3 (100-700 km) in a range 0,0-0,1 HGU, these variations do not render almost any influence on a superficial thermal stream.
