The Early Miocene Upper Marine Molasse of the German part of the Molasse Basin - a subsurface study. Sequence Stratigraphy, Depositional Environment and Architecture, 3D Basin Modeling
Abstract
The detailed investigation of the early Miocene (Upper Marine) Molasse of the German part of the Molasse Basin is based on the study logs from 72 wells which have been digitized with LogScan® (Briere Engineering) and on the reinterpretation of 14 seismic sections. The interpretation program Geographix® (Landmark Graphics) has been used to integrate all data into facies maps, cross sections and 3D model in order to reach an improved interpretation of the paleogeographic configuration, paleobathymetry and facies-distribution of the Upper Marine Molasse. These interpretations have been complemented by data available from literature. The Upper Marine Molasse (Obere Meeresmolasse = OMM) of the Northern Alpine Foreland Basin has been deposited in a narrow marine connection (the so-called “Burdigalian Seaway”) of the Mediterranean Sea with the Paratethys during the early to middle Miocene. Although numerous studies discuss the paleogeography, paleobathymetry, and facies-architecture of the OMM, additional data were required to improve our knowledge of the structural and stratigraphic configuration of the "Burdigalian Seaway". The deposition of the Upper Marine Molasse (OMM) was initated by a basin wide transgression during the Early Miocene (~ 20 Ma) that flooded the Alpine foredeep, generating shallow marine conditions between south-eastern France and Eastern Austria via Switzerland and Southern Germany. A sequence stratigraphic subdivision of the Upper Marine Molasse was suggested by Jin (1995) and Zweigel (1998) in the area of Eastern Bavaria. Five second order sequences modified from Jin (1995) have been recognized by Zweigel (1998). The aim of this work is to study in detail the Sequence 4, which was deposited during the early Miocene.
