Short Course - From rifting to drifting the mechanisms of continental lithosphere extension and rupture


Società Geologica Italiana

Professor Geoffroy Mohn Université de Cergy-Pontoise (France) Department Géosciences et Environnement - GEC Laboratory
When: 18th - 22th February 2019
Where: Dipartimento di Scienze, Sezione Geologia, Università "Roma Tre"
Blocco Aule - Largo San Leonardo Murialdo, 1 - Roma

The workshop will discuss different modes of extension of the continental lithosphere leading to plate rupture, using high quality offshore seismic data and onshore fossil analogue (Alps). Notably, this workshop will discuss our current understanding of rifting and breakup processes in the light of the recent IODP drilling results from the South China Sea. It will be associated with seismic exercises on rifted margins. An introduction on the influence of rift-inheritance for subsequent orogenic processes will be also presented.

Monday 18th of February, 9:30am to 12:30pm and 2pm to 3pm
  • Introduction and aim of the workshop: The mechanisms of extension of the continental lithosphere and breakup.
