geotermija Hungary and tektonofizika ' a red stain ' the Pannonsky hollow

F.Horvat, L.Bodri and P.Ottlik

The Summary. Hungary occupies the central part of the Pannonsky hollow. In the high-permeability adjournment filling a hollow, and in zones of gidrotermalno-active breaks in mesozoic karbonatnom the base the geothermal field is complicated by water circulation. Thanks to a successful arrangement and depth of those thirteen chinks on which the thermal stream was defined, all its values, except for one, are reliable: an error less than 25%. Because of complexity of exact definition of heat conductivity of clay deposits it was difficult to receive with sufficient accuracy of value of a thermal stream in a low part of Hungary. Fourteen newest estimations of a stream of heat have been received according to long-term, from 5 till 15 years, records of temperatures near a surface, the pas to depth from 20 to 200 see cards of distribution of temperature on various depths Were used also. These three sources of geothermal data create in aggregate quite good card of thermal streams in Hungary.

On a geothermal card of Europe the Pannonsky hollow is allocated as ' a red stain '. Geophysical and geological data allow to assume, that the maximum of a thermal stream is caused by a dome-shaped raising partially fused astenosfery. Surplus of heat in a raising, most likely, is generated poddviganiem litosfery along the Karpatsky arch.
