Abstract (in czech)
   This paper summarizes the results of low-temperature hydrothermal experiments in which solutions containing Cs, Rb, and Sr were allowed to react with medium-grained biotite granite from Podlesí (Krušné hory Mts., Czech Republic). The experiments were performed at 115 and 150 °C under < 0.5 kbar hydrostatic pressure, for durations of 1872?5562 hours. In these experiments, hydrothermal solutions containing Rb and Sr did not react with the rock-forming minerals in the granite. However, the Cs-containing solution did react with the rock-forming minerals, particularly the feldspars, to produce pollucite, a secondary Cs aluminosilicate. Pollucite could thus be used to delineate migration pathways of solutions through the granite samples. Three im-portant migration pathways were distinguished: microcracks, grain boundaries, and cleavage planes.
