MSc. Thesis in the Sedimentary Systems research group “Quantification of a catastrophic submarine Mass Transport Event in the Early Micoene of the Upper Austrian Molasse”
During the Oligocene and Early Miocene, the Upper Austrian Molasse Basin formed a narrow marine basin at the margin of the Paratethys. In the Early Miocene, the submarine strata of the Upper Austrian marine Molasse are characterized by a catastrophic mass wasting event at a large scale (Fig. 1, Hubbard et al., 2009). The laterally isolated occurrences of chaotic lithofacies are associated with mass-transport complexes and represent large raft blocks (several 100 m in diameter). Large raft blocks (several 100 m in diameter) slid down from the southern, tectonically active margin of the basin and into the basin-axial submarine channel belt. The distinct outline of the features in seismic- reflection data indicates that they traveled across the seafloor as coherent blocks. These olistoliths consist of predominantly of fine-grained laminated shale and sandstone. Single blocks are large enough to serve as individual natural gas reservoirs.
In this study, we propose to investigate this basin-wide catastrophic mass wasting and interpret its causes. The MSc candidate will quantify the distribution and volume of the raft blocks by interpretation a large (3300m km2) 3D-seismic reflection cube, well data, and sediment core. Furthermore, we will constrain the temporal occurrence of this large-scale, catastrophic mass wasting events (in cooperation with Gero Fischer).
This project will be primarily supervised by Anne Bernhardt. The MSc student will join a research team (1 PhD student, 2MSc students, 2 professors) investigating different aspects of the Molasse Basin strata. The project is partly financed by the Rohöl-Aufsuchungs AG (RAG). A final presentation of the study results in the RAG headquarters in downtown Vienna will take place in March 2018.
