Abstract (in english)
   The Lower Carboniferous Culm Basin is part of the European Variscan foreland basin. Garnet is an abundant heavy mineral at all stratigraphic levels of the Culm sediments (the Protivanov, Rozstání and Myslejovice Formation from base to top). This paper compares the major element (electron microprobe) and trace element (LA-ICP-MS) compositions of garnet for the purpose of studying the provenance of the Culm sediments. The polymict garnet assemblages ranging from the Protivanov to lower part of the Myslejovice Formation (Goniatite zones Pe-Go) pass into oligomict ones dominated by pyropealmandine garnets (uppermost part of the Myslejovice Formation; Goniatite zones Go-Go). As the predominant low-grossular pyropealmandines from oligomict garnet assemblages are very uniform and homogeneous in major element composition, we studied their trace element composition and zoning.
