英文摘要: 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 15km. 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. 400km to the SE across the Pannonian Basin, with an average of 67km/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. © 2012 Elsevier B.V.
