Abstract (in czech)
Abstract (in english)
   Two microscopic types occur in the Paleozoic rocks of the Konice-Mladeč unit. The optical properties of the vitrinite-like maceral correspond to the anthracite rank. The other type of maceral is equivalent to meta-anthracite rank and is considered either as redeposited or of non-humic origin. The low increase of thermal maturity with depth indicates rather low than high paleo-geothermal gradient and burial to depth of several km. Little or no difference is observed among the lithostratigraphic units, basinal and transitional facial developments and geographic position.
