Dolomite marbles at contact of the Moldanubicum and Moravicum in the area between Jasenice and Oslavany

Dolomite marbles at the contact of the Moldanubicum and Moravicum in the area between Jasenice and Oslavany were studied. The observed mineral assemblages, metamorphic zonality, chemical composition of dolomite marbles and lithostratigraphy of the rock sequences containing marble bodies indicate: (1) The studied dolomite marbles of the Moldanubicum are nearly the same as the dolomite ones of the Strážek Moldanubicum, (2) The dolomite marble from Ketkovice-Chvojnice (the Olešnice Unit) is very similar to dolomite marbles in the northern part of the Olešnice Unit. (3) Tectonic movements along the Náměšť Fault are younger than metamorphism M 2 and the course of this fault is not always identical with the overthrust of the Moldanubicum over the Moravicum. (4) The metamorphism M 2 is not younger than the overthrust.
