COG3 Seminar: Marc-Antoine Longpré (Queens College CUNY)

Marc-Antoine Longpré (Queens College CUNY)
Friday, March 9, 2018 - 10:00am to 11:00am

About the Speaker

Marc-Antoine Longpré's research interests lie where volcanology and igneous petrology mingle and mix. In the field, he examines and samples tephra and lava sequences to reconstruct the eruptive histories of volcanoes. In the lab, he analyzes the chemical composition of volcanic rocks and their constituents (volcanic glass, minerals and their inclusions) to decipher the dynamics of magma reservoir and eruption processes, such as magma differentiation, mixing and degassing, and the environmental consequences of volcanic eruptions. Topics include:

   •  Triggering mechanisms of explosive volcanic eruptions
   •  Architecture of magma plumbing systems
   •  Volatile element budget of magmas recorded by melt inclusions
   •  Sulfur in magmas
   •  Climatic and environmental impacts of volcanic eruptions
   •  Timescales of magmatic processes
   •  Geochronology, eruptive history and hazards assessment at individual volcanoes
   •  Giant landslides and their effects on ocean island volcanoes

About this Seminar

The Chemical Oceanography, Geology, Geochemistry, and Geobiology Seminar [COG3] is a student-run seminar series. Topics include chemical oceanography, geology, geochemistry, and geobiology. The seminars take place on Fridays from 10-11am in Building E25, Room 119, unless otherwise noted (term-time only).
