Dipping reflectors in the upper mantle are observed on reflection seismic data and, in some case, have been interpreted to represent mantle shear zones. It is not clear, however, how these shear zones develop and under what circumstances. Previous attempts to model strain localisation by strain softening in the ductile regime have failed to show the development of mantle shear zones. We present here results from a numerical model of lithospheric extension. The model uses an elasto-visco-plastic...[Show more]
