Abstract: Halostransk~ n4m. 19, 6SSR ABSTRACT. A review of the stratigraphy, facies, palaeo geography, and tectonic development of the Permian of the Bohemian Hassif is given. The Permian rocks of Bohemia and Moravia are of terrestrial origin and belong to the Variscan (central European) province according to the division of H. Fal ke. Regionally they are represented in the following areas: 1/ in the Sudetic region, 2/ in the Central and western Bohemian area, and 3/ in the Boskovice and Bla nice furrows. The Carboniferous/permian boundary lies partly in a continuous sequence, but in some areas a sedimentary break is developed. The palaeogeography is defined as the share of se diments of the different sedimentary environments on the composition of the sedimentary fill. The character of the sedimentary area and of its fill was mainly influenced by diastrophism and climate. The filling of the basins had a cyclic character. Diastrophic movements were connected with the final evolution of the Variscan orogeny. Volcanic activity was controlled also by cyclicity, and is manifested by the alternation of basic to intermediate and acid vol canism. The Late Palaeozoic volcanism culminated in the Autunian period, but in that time also was terminated. The volcanic centres are associated with the zones of
