From foundations to state-of-the-art in magma/mantle dynamics

We have been made aware of a convincing email scam that is focusing on our Programme and Workshop participants. Participants may receive an email from a firm called Expo Hotel Services (ehotelservices.org) to arrange accommodation for workshops and/or programmes. This might include a request to provide them with credit card information.

Workshop theme

This first workshop sets the scene for the rest of the four-month "Melt in the Mantle" programme. The workshop will review what we think we understand about mantle melting and melt transport, and what the big open questions are that remain. The workshop will bring together a diverse range of participants, including applied mathematicians, fluid dynamicists, petrologists, and geodynamicists, as well as other workers in related fields. It is only through such a broad interdisciplinary effort that progress will be made.

A large part of this workshop will be devoted to using ideas from continuum mechanics to understand melt segregation in the mantle. In particular, existing two-phase flow theories will be discussed, and their shortcomings exposed. The workshop will explore the connections between theories of two phase flow used in magma dynamics, and those in other fields (e.g. glaciology). Problems of mantle melting are intimately tied up with the dynamics of the mantle as a whole, and the workshop will contain a review of the relevant aspects of global mantle convection, and in particular the convective features that are associated with melting, such as mantle plumes and subduction zones. The workshop will survey the current state-of-the-art in mathematical methods for magma and mantle dynamics, with a review of both analytical and numerical approaches.

Understanding how much melt is produced in any given tectonic setting is fundamentally a question of thermodynamics, and the workshop will examine the challenges associated with describing the thermodynamics of multi-phase multi-component partially-molten rock. Observational constraints on mantle melting come from the petrology and geochemistry of rocks at the surface, and these observations will be carefully interrogated.
