    Karbon Appalachów i jego porównanie z karbonem Górnośląskiego oraz Lubelskiego Zagłębia Węglowego
    (Wydawnictwa AGH, 2007) Zdanowski, Albin
    The Carboniferous deposits occur generally on the entire territory of the United States of America. The region to be correlated is the West Virginia where numerous Carboniferous outcrops occur and they are detailed floristically documented. The studied region is located west of the Breward tectonic zone, the inner boundary of the Appalachian between the Late Palaeozoic Atlantic Plate and the Early Palaeozoic Central Plate. The Carboniferous macroflora documents the Late Mississippian (Serpukhovian/Namurian A) and the Late Pennsylvanian (Late Bashkirian-Early Moscovian). The documented stratigraphic gap the post-Chesterian surface in the studied region corresponds to the latest Mississippian and Early Pennsylvanian. In Polish coal basins it probably corresponds to the stratigraphic gap ascribed to the $H_1$ and $H_2$ goniatite zones. In both studied regions marine and paralic deposits with coal beds occur below the gap and limnic-fluvial deposits with coal beds and thick paralic deposits dominate just above it.
