Partial Melting Above the Mantle Transition Zone

Presented by: 
Sash Hier-Majumder Royal Holloway, University of London
Tuesday 16th February 2016 - 11:30 to 12:30
INI Seminar Room 1
Recent seismic observations indicate the presence of a low velocity layer above the mantle transition zone. Marked by a reduction of shear wave speed, the top of this layer is generally detected around a depth of 350 km. In this talk, I will present an analysis of seismic data quantifying the amount of melt present in this region, stability of this partially molten layer over geologic time, and the possible origin of the layer in the context of crystallization of the Earth's mantle from a magma ocean.
