The foreland state at the onset of the flexurally induced transgression: data from provenance analysis at the peripheral Carpathian Foredeep (Czech Republic)

Popis výsledku v původním jazyce

The Žerotice Formation recognised in a confined area NE–SE of Znojmo represents a basal member ofthe sedimentary succession of the southwestern margin of the Carpathian Foredeep in Moravia (Czech Republic).Two facies associations were recognised within the formation. The first one mantles the pre-Neogene basement withan irregular unconformity, reflects arid climatic conditions and deposition of episodic shallow, high-energy stream flowsand/or mass flows (alluvial to fluvial deposits). The second facies association is interpreted as lagoonal to distalflood plain deposits. The barren unfossiliferous deposits of the Žerotice Formation are covered by nearshore marineEggenburgian deposits. The boundary between these deposits represents a sequence boundary (i.e. the basal forebulgeunconformity). Detailed provenance studies of successive beds below and above this sequence boundary showeddifferences in the source area and paleodrainage. Both the local primary crystalline rocks (Moravian and MoldanubianUnit, Thaya Batholith) and older sedimentary cover (especially Permo–Carboniferous sedimentary rocks) form the sourceof the Žerotice Formation. All these geological units are located only a few km away from the preserved areal extent ofthe deposits of the Žerotice Formation (short transport and a local source). The source areas of the overlying marineEggenburgian beds are located far more to the W and NW in the Moldanubian and Moravian Units (longer transport,extended source area). Local confined preservation of the Žerotice Formation is preliminarily explained as connectedwith a tectonically predisposed paleovalley.
