The VICCO talk is held by: Håkon Austrheim (Professor Emeritus, Department of Geosciences, University of Oslo), and has this title/topic:
Seismic Pumping, Abyssal Weathering and Carbonation of Peridotite along a slow Spreading Ridge
Abstract: Slow spreading ridges are associated with large bodies of weathered (brownstone facies) peridotite. A seismically processed peridotite has high porosity and minerals that are strongly out of equilibrium in contact with cold oxygen rich water. It is argued that this internal brownstone facies weathering, enhanced by seismic pumping, represents a globally significant, yet overlooked, geochemical reactor that impacts the Mg, Ca and C cycles.

About the VICCO+ seminar series
The seminars are open for everyone interested, and especially students are welcome. The talks in VICCO+ seminar series are offered by the The VICCO centre, Dept. of Geosciences, University of Oslo.
The VICCO+ talk seminar series are normally held in the Geology Building, at UiO's campus Blindern, see this map.
The Co-ordinator for the talks is
