Defining the Lithosphere-Asthenosphere
Boundary Beneath Continents
ESF Exploratory Workshop
3-5 June 2009
Dublin Institute for Advanced Studies
10 Burlington Road, Dublin 4
The lithosphere-asthenosphere boundary (LAB) is the most extensive plate boundary on the planet, and, although it is an active plate boundary, beneath the continents it is relatively cryptic compared to other first-order structural subdivisions of the Earth. This workshop will bring together geophysicists, geochemists, petrologists and mineral physicists to focus on this boundary and its definition using the various proxies that exist.
The objectives of the workshop are:
to discuss and evaluate critically a number of widely used proxies for the LAB;
to compare these proxies with each other and with realistic rheological models of the “true” (i.e., mechanical) lithosphere;
to assess the extent to which different techniques sense the same feature, and if so, to document its intrinsic characteristics; and,
to plan for the future, by deciding what multi-disciplinary experiments need to be performed at which locations.
