Map development of a thermal stream. For map development we involved all data on a thermal stream, except for unreliable value of points 8 and close to it with estimations of a thermal stream in 52 мВт/м2. Not considering values 5 (Nadlendel) and 6, all other definitions of a thermal stream, most likely, are not strongly deformed by water circulation. They are made far from gidrotermalno-active breaks mesozoic karbonatnogo a complex or executed more low strongly porous verhnepannonskih - chetvertichnyh layers. We believe, that the general error of 13 standard definitions of a thermal stream and 14 estimations is less than 25 and 30% accordingly. As temperature cards quite well display relative changes of temperature of the Pannonsky hollow, they can be taken into consideration at map development of a thermal stream. As average sizes for knots of a square grid on six horizons (0,5, 1,0, and #8230; 3,0 km) we used values from card SHtegeny 1381 and have considered reliable an estimation of average temperature on depth of 1,5 km. On this depth revolting action of movement of water slightly and thermal effect of chisel operations is not too great. On the basis of this series of data we have calculated a card of a gradient of temperature, and also a card of a thermal stream in the assumption, that heat conductivity a constant and is equal 1,67 Vt / (м*К). We have received surprising result: the huge majority of the given measurements and estimations of a thermal stream will be co-ordinated with this calculated card. Some amendments are necessary for a northeast part of Hungary where the calculated values it is less, than measured. Really, in this area average heat conductivity obviously above than 1,67 Vt / (м*К). Constructed by the technique accepted by us the card of a thermal stream of Hungary reflects also some local features, for example in a southeast part of the Big Hungarian lowland. All territory of Hungary is characterised by high value of a thermal stream and its strong negative correlation with capacity of adjournment filling a hollow. Correlation is caused by two circumstances: first, smaller thickness of deposits, thanks to higher position of well spending base, and, secondly, small cooling effect osadkonakoplenija, not considered in data of a thermal stream. The big capacity of sedimentary thickness can explain close to normal value of a thermal stream for Small Hungarian lowland (70-80 мВт/м2) and the same rather low values forming a narrow strip in a southeast part of the Big Hungarian lowland. All sites in an isoline 100 мВт/м2 are connected with base raisings. The maximum of values of the thermal stream, dated for lake Heviz (a southern bath of lake Balaton), is connected with gidrotermalno an active break.
