Odnosi toplinske provodljivosti stratigrafskih jedinica iz šireg područja Zagreba
Thermal conductivity (KTV) of geological formations is one of the parameters responsible for the propagation of the heat under the earth surface. During geothermal investigations in the broader area of the Croatian capital of Zagreb the thermal conductivity was measured on the rock samples from the surface and the boreholes. The results of the measurements are presented in this work and used as a basis for calculations of the thermal conductivity of distinct geological formations within the investigated area. It was found out that the values of the thermal conductivity of the rocks in the investigated area vary greatly. The measurements are within the well known scope for certain rock types. The thermal conductivity of the rocks from the Tertiary units corresponds with the average values being typical for such kind of rocks, while the basement carbonate rocks are characterized by the values being by 1 W/K-1m-1 higher than the average. After comparing the thermal conductivity of the stratigraphic units in the broader area of Zagreb it has been established that the values of the thermal conductivity of geological formations in the investigated area are also very different, and that they generally rise with their age. The relative relationships show that the Quaternary, Pliocene and Tertiary sedimentary rocks act as thermal insulators, while Triassic rocks behave as the heat conductor.
