Tartalmi leírás:
The basin of giant Lake Pannon in Central Europe was filled by forward accretion of sediment packages during
the Late Miocene and Early Pliocene. Successive positions of the shelf-margin are represented by a series of
clinoforms in seismic profiles. The height of the clinoforms (and thus the inferred paleo water depth) is
200?600 m in the successions; the width of the slope, measured from the shelf-break down to the toe of
slope, varies between 5 and 15 km. Geographical position of successive shelf-margin slopes indicates that
about 2/3 of the basin area was filled by sediment transport systems supplying sediments from the NW,
from the Alps and Western Carpathians. The first shelf-margin slope was built by the paleo-Danube in the
Kisalföld/Danube sub-basin about 10 Ma ago, and during the subsequent 6 Ma it prograded ca. 400 km to
the SE across the Pannonian Basin, with an average of 67 km/Ma slope advance. The most significant agent
of this shelf growth was the sediment dispersal system of the paleo-Danube, hence we designate this northwestern
shelf the paleo-Danube shelf. The northeastern part of Lake Pannon was filled by the paleo-Tisza system,
supplying sediments from the Northeastern and Eastern Carpathians. Additional local systems carried
sediments from E to W along the eastern margin and S to N along the southern margin of the Pannonian
Basin, respectively. The deep-water environment disappeared from the Pannonian Basin and the endemic,
brackish biota of Lake Pannon went extinct probably 4 Ma ago, when the paleo-Danube shelf margin and a
(yet unidentified) shelf margin prograding in the opposite direction met in the southeastern corner of the
Pannonian Basin.
