Geodynamics of the Alps-Mediterranean mountain belts and basins (January 2019)

"Understanding the central Alpine-Mediterranean chain – a Primer"

Program

Participants will be introduced to mountain-building processes in the Alps and their adjacent chains and basins, as well as analogous mountain belts in other parts of the world. The course is directed especially at non-geologists in AlpArray to show how knowledge of rocks exposed at the surface is used to constrain the structure and evolution of the Alpine chains and their forelands. It provides a survey of the parts of the Alpine chain in the central Mediterranean area (Alps, Apennines, Carpathians, Dinarides) and discusses models of rifting, spreading, subduction and collision. Course material will draw heavily on the experience of the lecturers, who will review case studies and discuss the advantages, but also the pitfalls of state-of-the-art methods used to constrain the motion history leading to the present mountain belts and basins.

Early career scientists (postdocs and PhDs) in the SPP are expected to attend; their travel and hotel costs will be covered by the SPP (keep your receipts and send them after the workshop to emanuel.kaestle@fu-berlin.de together with your IBAN and private address). The course is also open to all members of the AlpArray community.

Location: Freie Universität Berlin, Geocampus Lankwitz, Malteserstrasse 74-100, Haus C, Raum C014 (Bus stop "Emmichstrasse", Bus X83, click here for a plan of how to get to the building).

We recommend you to take a BnB/Hotel close to Rathaus Steglitz.

If you have questions please contact Emanuel Kästle (emanuel.kaestle@fu-berlin.de).
