Temperature a gradient in ispanii. Temperatures in earth crust

you are: Temperature a gradient in ispanii

Deep temperature profiles of earth crust have been calculated by means of the model offered by the Plenty, etc., for three typical areas. These calculations are based on following assumptions: capacity of sedimentary thickness prenebrezhimo is small and does not influence in the field of temperatures; heat conductivity of the top granite bark is equal 2,51 Vt / (м*К); heat conductivity of the bottom bark makes 2,1 Vt / (м*К) and does not depend on temperature; heat-generation Of granite breeds is equaled 2,5 мкВт/м3; teplogeneratsija in the bottom bark it is equal 0,42 мкВт/м3.

Between two extreme cases (Meseta and Cartagena) which differ on a thermal stream on 13 мВт/м2, is available a difference and in capacities of the bark, equal 9 km. In Cartagena in comparison with Mesetoj the contribution of a thermal stream from the top part of a bark (a granite layer) decreases with 65 to 30 мВт/м2; however it is much compensated by increase in a thermal stream from the bottom part of a bark and the top cloak. In particular, under the Mediterranean coast the thermal stream from the top cloak considerably increases in more thin bark: from 13 to 56 мВт/м2. Similarly the temperature at level of section Mohorovichicha raises from 720 ° With on depth of 36 km under Mesetoj to 880 ° With on depth of 27 km near Cartagena. Though these results also are only preliminary, they, apparently, quite correspond to the similar phenomena observed in other regions of Europe.

Geothermal researches and measurements of a thermal stream have been continued in 1979 when began possible to use more detailed given interpretations of a structure of earth crust along profile GSZ in northeast Spain where there are some distinct anomalies in distribution of a thermal stream.
