Jeudi 28 juin à 14h en salle des séminaires, Jayananda Mudlappa (Université d’Hyderabad (Inde)) présentera ses travaux sur : Archean crust formation and continental growth: Insights from the Dharwar craton, southern India. Le professeur Jayananda Mudlappa sera au LMV pour travailler avec Martin Guitreau sur le projet ANR Zircontinents. Il restera au labo jusqu’au 6 juillet.…
Assessing hazards from small-volume Pyroclastic Density Currents (PDCs): a multi-disciplinary approach with emphasis on their potential for avulsion Dr Sylvain Charbonnier, School of Geosciences, University of South Florida, USA Small-volume (< 0.5 km3) pyroclastic density currents (PDCs) occur relatively frequently and pose severe threats to surrounding populations and infrastructures at active volcanoes. They are responsible…
Title: Extremely early recurrence of intraplate fault rupture following the 2011 Tohoku-oki earthquake Abstract: Intraplate earthquakes on a fault in the Earth’s upper crust commonly recur in thousand years or longer. The 2011 M9 Tohoku-oki earthquake triggered the activation of intraplate earthquakes in northern Kanto, Japan, including two M6 events on 19 March 2011 and…
Titre: Imagerie des zones actives profondes par détermination du point de Curie Détecter les zones actives en profondeur est une nécessité mais aussi un challenge dans la compréhension des systèmes volcaniques au sens large. Imager la distribution des anomalies thermiques est dans ce sens fondamental pour caractériser l’évolution des zones de stockage, les modalités de transfert des magmas, et…
TITRE: Application of multiple sulfur isotopes in geochemistry. Résumé: The analysis of all four sulfur isotopes has the potential to provide information about reaction pathways that differentiate equilibrium from kinetic effects as well as provide information that can be used as tracers of geochemical processes. This talk will review the basic principles that control the nature…
