ArgChiBolVolc Project

I am delighted to announce that I am in South America for 6 weeks for a project, ArgChiBolVolc, funded by the INSU Institute of French CNRS, in collaboration with Pablo Grosse (CONICET and Miguel Lillo Foundation, Argentina). The main field trip objective is to sample lavas from the Mio-Pléistocene volcanoes of the Argentine and Chilean Puna (Central Volcanic Zone of the Andes). Back at the GEOPS laboratory (Université Paris-Saclay), these rocks will be dated by the unspiked K-Ar method, and the morphology of the volcanoes will be analysed using digital topography (DEM). One of the objectives of this project is to establish correlations between the degree of dismantling of these volcanoes and the climatic variations that have prevailed since their construction.
