Research Topics


Neotectonics:
  • Tectonosedimentary basin evolution as a proxy for plate tectonic processes
  • Paleo- and archeoseismology
  • Kinematic analysis/modelling (stress inversion)
Sedimentology:
  • Controls on sediment supply (using analogue and numerical models)
  • Sequence Stratigraphy of deltaic systems
  • Gamma-ray spectrometry as tool for cyclostratigraphy

Ongoing Research Projects


Neotectonic basin evolution in SW Turkey

This DFG funded study into sedimentary basins in the Fethiye-Burdur Fault Zone (FBFZ) uses tectonosedimentary information from different observational time scales as a proxy for the relative contribution of collision-related processes. For the geological time it involves multidisciplinary basin analysis. For the historic time scale archeoseismological evidence from Hellenistic, Roman or Ottoman settlements will be used to detect fault activity. Present-day data involves actual displacement rates using GPS measurements to enable validation of field-based tectonic models. Staff involved: J. ten Veen, A. Immenhauser, M. Sintubin (Leuven, B), M . Alçiçek (Denizli, TR), L. Maul (Weimar), C, Kreemer (Reno, USA)

Climatic control on fan delta architecture

Central in this study is the question of how and to which extent climate variations control depositional architecture of a basin fill. In order to see which Milankovitch periodicities are likely to be represented we focus on fan-delta settings. These warrant a short sink-to-source distance such that uncertainties concerning the translation of river sediment load into sediment supply are small. In order to quantify the effects of various Milankovitch cycles on fan delta behaviour we will perform physical, scaled experiments in the ”EUROTANK” flume tank facility. Model results will be compared with field data from prograding fan-delta bodies at the margin of the Neogene Sitia Basin (Crete, Greece). Staff involved: J. ten Veen, G. Postma (Utrecht, NL).

High-resolution sequence stratigraphy of stacked fan deltas

Fan deltas are sensitive recorders of of depositional variability. In particular the nature of the topset- and prodelta sequences and their correlation will give important information on controls on sediment supply and accommodation changes. We study Plio-Pleistocene fan deltas in the Gulf of Corinth and gamma-ray spectrometry, XRD analysis, and palynofacies to uncover climatic signals and variations in continental influence in the prodelta facies. Results will be incorporated into a conceptual sequence stratigraphic framework. Staff involved: J. ten Veen, U. Heimhofer, N. Rameil, P. Schulte (Univ. Erlangen).

Teaching


Beckenentwicklung und Sequenzestratigraphie (Basin Analysis and Sequence Stratigraphy)

outline: This course is designed to introduce the ways in which sedimentary basins develop and fill, and how they and their contents can be used for a variety of applied purposes, including plate tectonic and paleogeographic reconstructions, the location and efficient production of natural resources, and understanding the global, regional and local controls on depositional systems, surface processes and stratigraphic architecture. Course documents (for those who are authorized) through Blackboard

Geologische Karten und Profile (Maps and Cross Sections)

absicht: Die Veranstaltung soll die Anfänger der Studiengang Geowissenschaften mit den wesentlichen Merkmalen geologischer Karten und ihrer Erstellung vertraut machen. Hauptziel ist es, das Verständnis dreidimensionaler geologischer Strukturen aus ihren zweidimensionalen Anschnitten an der Oberfläche zu bilden. Räumlich-zeitliches Vorstellungsvermögen stellt in vielen Teilrichtungen der Geowissenschaften eine wichtige Kernkompetenz dar. Die Teilnehmer lernen, die geologische Entwicklung eines Gebietes einschließlich der relativen zeitlichen Abfolge einzelner Ereignisse aus geologischen Karten zu interpretieren. Ein weiteres wichtiges Ziel ist die räumliche Rekonstruktion geologischer Einheiten aus isolierten Datenpunkten an der Oberfläche bzw. aus dem Untergrund. Hierzu werden unterschiedliche Methoden wie geometrische Konstruktion und trigonometrische Berechnung vermittelt. Kursunterlagen in Blackboard
