The 4th international 'Serpentine Days' Workshop was recently held in the Lazaret resort in Sète (Southern France) from 25 to 29 September 2016. It was supported by the Société Française de Minéralogie et de Cristallographie (SFMC), Géosciences Montpellier, the CNRS, the Université de Montpellier, The Institut des Origines and the Université de Lyon, the région Occitanie Pyrénées-Méditerranée, and the Deep Carbon Observatory.
The next Serpentine Days will be organized by Marco Scambelluri (U. Genova, Italy), Alexis Templeton (University of Colorado at Boulder), Alberto Vitale-Brovarone (IMPMC-CNRS Paris), Oliver Plümper (Utrecht University)and Nadège Hilaire (Lille University) in 2020. Stay tuned!
The programme was divided in 8 sessions:
It was complemented by two poster sessions:
All sessions were introduced by outstanding keynote speakers who ignited a passionate time for discussion that continued during coffee breaks and poster sessions. The nearby beach and the splendid weather were much appreciated during spare time between the morning and the afternoon sessions. Participants also enjoyed a gourmand «aperitif Sétois» on the night of the second day.
To complete the workshop a two-day field trip to the Pyrénées was led by Yves Lagabrielle (Univ. Rennes, France) and Michel de Saint-Blanquat (Univ. Paul Sabatier – Toulouse, France), assisted by Ricardo Asti and Jessica Uzel. The field trip was joined by more than 40 participants, and allowed them to discover field evidences of mantle denudation associated to cretaceous rifting event in the North Pyrenean Zone (Étang de Lers and Bestiac). Special attention was given to the carbonatation and serpentinization imprint in the lherzolitic bodies, and to its connection with the high-temperature and low-pressure metamorphic event recorded in scapolite-bearing marbles, anorthite-bearing metaevaporites and intriguing sapphirine-bearing breccias. Once more the good weather accompanied us for two days allowing a gentle walk on mantle tectono-sedimentary contacts, precisely illustrated by Yves with talented in situ drawings.
