Abstract (in english)
   Short description and characteristics of several types of thorium mineralization in the Bohemian Massif are given: orthogneisses with 200 ppm Th (Moldanubicum), Permian volcanics in the IntraSudetic basin (U-Th-V, up to 450 ppm Th), REE-Th pegmatites (Moldanubicum), metasomatic (the Sudety Mts.) and Ordovician Ti-Zr-Th-REE paleo-placers (Saxothuringicum), recent Ti-zr-Th-REE-Nb placers (Lužnice River, S Bohemia), vein type - Moldanubicum (Th-U). Reserves of 87 tons Th have been calculated in the Estimated Additional II category at Budišov (vein-type deposit in melanosyeites)
