Abstract (in english)
   Black shales and shaly intercalations in carbonates were investigates in Konice-Mladeč area in the northern Drahany Upland. Reflectance of vitrinite-like macerals was measured in plane-polarised light. Two types of maceral were observed in the polished surfaces, representing a vitrinite-like kerogen of higher anthracite rank (R max=3.3-3.0 %) and a strongly bireflectant kerogen with higher maximum reflectance (R max=6.0-9.3 %) of meta-anthracite rank. Thermal maturity is similar in all stratigraphic units, depth levels and partial regions within the Konice area. The R max value suggest very low-grade metamorphism at temperature approximately ranging from 240 to 360 °C
