The red-algal facies of the Lower Badenian limestones of the Carpathian Foredeep in Moravia (Czech Republic)
Abstract
The existing data on Lower Badenian red-algal limestones from the Carpathian Foredeep in Moravia (Czech Republic), up to now dispersed in various publications and manuscripts, are summarized for the first time. They are discussed and interpreted according to contemporary carbonate sedimentology and actuopaleontology together with the latest results of field research and macro-/microscopic studies from 16 outcrops (Prace Hill, Zidlochovice, Podbrezice, Bacov, Sudice, Pametice, Sebranice, Svetla u Boskovic, Tisnov-Ochoz, Repka, Lomnice, Olomouc, Hostim, Rebesovice, Blucina and Telnice). The Moravian red-algal limestones originated in a warm-temperate to subtropical climate and, in contrast to the Polish part of the Carpathian Foredeep, their areal extent and thickness are distinctly smaller due to the highly varied basin configuration. The predominating facies of red-algal limestones are biodetrital grainstones (fine-grained grainstones and bioclastic grainstones), coralline branch rudstones–floatstones and rhodolith rudstones. Red-algal limestones on the west and northwest margins of the preserved Carpathian Foredeep in Moravia are connected with the prograding coast line, and their positions in the profiles are not necessarily isochronous. At the eastern margin of the Carpathian Foredeep (immediately in front of the flysch nappes), important role of the redeposition of the red-algal limestones into more internal parts of the basin is supposed.
