 Abstract: The boron contents of the Westphalian C to Upper Stephanian claystones, siltstones and tuffaceous rocks of the Carboniferous Basins of Central Bohemia were studied. The conclusion can be drawn that the environment of these sediments origin was of a freshwater character. This is consistent with most geological investigations so far carried out in this area. The higher boron contents have been established in red-colored sediments (the Týnec and Líně Formations). The drier rather arid climate was responsible for a more intensive desiccation of the basins, and, accordingly, the increased concentration of salts in the water of these basins; this was also reflected in the boron contents of the clay minerals.
