   Carboniferous outliers are found west of the late Carboniferous West Bohemian basins and also south of the West and Central Bohemian basins. The West Bohemian group is Asturian (= Westphalian D) or younger and is notably coal-bearing, the other group of outliers consists mostly of coal-bearing upper Carboniferous volcaniclastic rocks of Bolsovian (= Westphalian C) and/or Asturian age. They form a discontinuous belt extending through the area between and around the towns of Merklín and Beroun. These rocks are underlain chiefly by rocks of ages varying from the Neoproterozoic or Cambrian up to the Ordovician. If the nappe structure of the Barrandian Lower Paleozoic proposed by Melichar and Hladil (e.g. 1999) is not widely present, then it can be assumed that as much as 1850 m of Lower Paleozoic sediments and volcanics could have been eroded prior to the onset of sedimentation of the Bolsovian rocks. In the upper Carboniferous outliers near Mirošov, Skořice and Kamenný Újezd, where sedime
   ntation began as late as in the Asturian, the thickness of eroded deposits might have been even greater, reaching as much as 3150 m.
