you are: the Preliminary card of a thermal stream gretsii

New data. In these measurements it was impossible to estimate the real time necessary for achievement of equilibrium temperature in all cases. In practice all mentioned measurements have been almost always received soon after the termination of drilling and circulation of a chisel solution. Therefore time necessary that at a face of a chink the true temperature was restored, was not. Data at numbers 35-37 have been received by Geothermal branch of Institute of geological researches and mining (Athenes, Greece). Data 38 and 39 are received by Geothermal branch of company RRS on island Melos.

Many chinks have been drilled in nontight adjournment where circulation of underground waters is possible. Some of chinks have been drilled in areas with well expressed disjunctive tectonics where, apparently, exist konvektivnye movements of thermal waters. It is doubtless in continental area of an active Egejsky volcanic arch. In this area existence of an abnormal thermal stream is underlined by increase of the gradient caused konvektivnoj by circulation of a fluid, existence of thermal waters and fumarolamp.

The Arrangement of boreholes is shown on a card of a thermal stream according to their code numbers. We had no possibility to spend direct measurements of factor of heat conductivity on samples of rocks from various depths from boreholes. For this reason the given parametre was defined by the analysis litologicheskogo a chink profile according to capacity of each separate layer of the same structure. The average factor of heat conductivity for each chink was counted up at use of the published values of heat conductivity of the typical breeds opened with the given chink.
