WebThe base of the lithosphere, designated as the lithosphere-asthenosphere boundary (LAB), may thus be characterised by different physical fields: temperature, viscosity, strain rate and velocity. The LABs as defined by these different fields are investigated here using thermo-mechanical models of plate and upper mantle dynamics, either in a transient … Web11 apr. 2024 · Numerical simulations suggested that edge-driven convection presumably occurred at a lithospheric step near the plume before the collision of the plume at the lithosphere–asthenosphere boundary (Duvernay et al., 2024); when a lithospheric step between the LT and HT2 zones was present, edge-driven convection would have … Web22 mrt. 2012 · The lithosphere-asthenosphere boundary, or LAB, represents the transition from hot, convecting mantle asthenosphere to overlying cold and rigid lithosphere.
