Constraints on the S wave velocity structure in a continental shield from surface wave data: Comparing linerarized least squares inversion and the direct search Neighbourhood Algorithm
In their study of upper mantle structure beneath the Paraná Basin of SE Brazil, Snoke and James  concluded, on the basis of a linearized least squares inversion (LLSI) of surface wave dispersion data, that a strong (5% contrast) low-velocity zone (
