DI006:
Diverse perspectives on the lithosphere and the asthenosphere





Session ID#: 23581

Session Description:
The lithosphere-asthenosphere boundary (LAB) separates Earth’s rigid tectonic plates from the underlying convecting mantle. Tractions, thermal gradients, compositional differentiation, fluid/melt accumulation, crystallographic fabrics, and grain size heterogeneity have all been suggested to occur at (or near) this interface. How this boundary is expressed in different tectonic settings and how it relates to other seismic and magnetotelluric discontinuities including the Moho and mid-lithospheric discontinuities (MLDs) is a topic of ongoing vigorous debate. We will focus on the lithosphere-asthenosphere system in a variety of settings including but not limited to continents, oceans, margins, rifts, ridges, hotspots, plumes, and subduction zones. We welcome research contributions from diverse fields, including but not limited to seismology, magnetotellurics, petrology/mineralogy, dynamical modelling, and mineral physics.
