Lithosphere Dynamics (Gekoppelte Geoprozesse in der Lithosphäre, MGPH1.1.1, MGPH1.1.2) Prof. Dr. N. Kukowski
Thursday, 11:00 am – 12:30 pm, lecture, PR2; practice time (prepare and run experiment*) to be discussed Earth's lithosphere, i.e. its „outer shell”, is shaped by deformation processes acting on very variable spatio-temporal scales. Plate tectonic processes leading to transient configurations of oceans and continents determine the large-scale structure of the lithosphere, whereas processes acting on the scale of individual pores seem to be important to understand slip along fault zones, accumulation of resources, or fluid transport, just to name a few. According to the wide range of pressure-temperature conditions prevalent in the lithosphere, and the dependence of rheology on these state variables, processes responsible for shaping the lithosphere act on very different spatio-temporal scales. Further, most of these processes are linked with each other, resulting in complicated feedbacks, as the lithosphere is highly heterogeneous. In the framework of this course, we will discuss lithospheric processes and their inter-relations. We will start with processes in the shallow subsurface and undertake a journey towards processes affecting the entire lithosphere. Each lecture will be complemented by discussion among all participants. To do so, for each topic there will be about three questions which should be addressed during the discussions.
Practise will deal with experimental work, poster preparation and presentation. Each participant will contribute to an analogue experiment and preparation of a poster dealing with a topic related to this class or the experiments. Before that we will deal with concepts how to layout a good poster, suitable software etc. The content of the poster, its layout, and the related oral presentation will be the prerequisite to get credit points. In addition, active participation in discussion and distribute posters among participants is strongly encouraged.
We plan for the following content and schedule in winter semester 2018/2019: 18.10. Organisational matters, planning (experiments*, posters) 01.11. Consolidation and subsidence 08.11. Poro-elasticity 15.11. Mountain Building, climate, and critical taper theory I 29.11. Mountain Building, climate, and critical taper theory II 06.12. How to prepare a scientific poster/analogue experiment 13.12. Basin dynamics 20.12. State of stress in the lithosphere (including world stress map) 10.01. Role of fluids in crustal mechanics 17.01. Lower crust processes 24.01. Lithospheric mantle 31.01. Lithosphere deformation at a whole including ”Christmas trees” etc. 07.02. Lithosphere deformation at a whole (diapirism)
This class is open for all interested students, e.g. of geophysics, physics, geology, geo-informatics, biogeosciences, as well as other study programmes; Language German or English
* Preparation and running of a physical analogue experiment needs at least several hours – therefore we figure out one or two days the lab work, which can be also later in February or early March
