. Young et al. (2013a) apply a transdimensional Bayesian inversion scheme to retrieve 3-D crustal shear wave velocity variations from interstation phase dispersion curves derived from ambient noise data. Distinct velocity anomalies can be tied to a number of known surface features including the Torrens Hinge Zone or THZ, Gawler Craton and Curnamona Province (see Fig. 1 and Fig. 2).
