Geochemistry of the subrecent polygenetic pseudochernozem in the aeolian sands at the confluence Dyje and Morava rivers ("Barvínkův hrúd")
Abstract
In the SE surroundings of the Great Moravian site Břeclav-Pohansko the occurrences of aeolian sands in the valleys of the Morava and Dyje Rivers are characteristic. The sands forming dune clusters typically overlie the gravels and sands of the Pleniglacial valley terrace and are dated to Late Glacial, probably to younger Dryas. On the dunes Mesolithic to Slavonic settlements were identified. Complex development of the sand dunes is demonstrated by a subfossil soil (polygenetic pseudochernozem) which evidence the existence of some hiatuses in an aeolian deposition. Youngest Holocene sediments in the area are flood (overbank) silta and loams.
