Fluvial deposits of the St. Marein Freischling Formation insights into initial depositional processes on the distal external margin of the Alpine Carpathian Foredeep in Lower Austria

Popis výsledku v původním jazyce

In the SE Bohemian Massif of Lower Austria sandy and gravelly fluvial deposits of the St. Marein Freischling Formation (Oligocene Early Miocene) are reflecting a braided channel system. Eleven lithofacies and four facies associations/architectural elements (gravelly channel dunes and bars, channels, sandy channel dunes and abandoned channels) were recognised. A network of relatively shallow streams with seasonal fluctuations in the discharge are supposed. The episodic character of transport, erosion anddeposition could reflect changes in climatic conditions. Provenance studies (pebble petrography, heavy minerals), evaluation of pebble size, shape and roundness, and paleocurrent data point at two parts of the fluvial system. For the main fluvial systema general transport from west to east can be supposed, which finally turned against the south in the surroundings of Horn. Tributaries both from north and south ended in the west-east reach of the main river.
