Lithospheric structure beneath the Zagros collision zone resolved by non-linear teleseismic tomography [PDF]
, 2011 The upper-mantle structure across the Zagros collision zone, in southwest Iran, is investigated using a non-linear weighted damped least-squares teleseismic tomography approach. The resolution of the structures/transitions in the upper mantle is enhanced
