Konduktivnyj a thermal stream in islandii. The Summary

you are: Konduktivnyj a thermal stream in islandii

Definition konduktivnogo a thermal stream on superficial boreholes becomes complicated revolting influence konvektivnyh the hydrothermal systems, mainly the close neighbourhood of superficial geothermal displays. Besides, within the youngest sites of an axial zone where superficial breeds possess high permeability, the temperature field of the top horizons of earth crust is sharply broken by movement of cold subsoil waters by gravity.

Attempt to make the distribution scheme konduktivnogo a thermal stream Has been undertaken; thus data were carefully selected, that, how much it is possible, to avoid thermal influence konvektirujushchej water. The main criteria of selection of chinks for this purpose is a linearity of temperature profiles, an arrangement of a chink outside of known hydrothermal systems. Certainly, always there is a probability of that the hydrothermal system can appear more deeply a chink face, but such systems if they are, should be shown, apparently, as a deviation from the general natural picture of distribution of a thermal stream.

In relation to each separate chink heat conductivity of breeds is unknown, but litologichesky the structure of breeds in the majority of chinks is identical, therefore on values of gradients it is possible to make accurate enough representation about change of a thermal stream from one chink to another. For measurements of factor of heat conductivity 150 images have been selected approximately; the spent measurements (the neopublished data of the Pole, Kononova and Dzhessopa) have shown, that value nearby 1,7 Vt / (м*К) can, possibly to be considered representative as average value for the typical chink drilled in earth crust in territory of Iceland. This value also was used for an estimation of a thermal stream.
