“…These values are within common estimates for Precambrian and Paleozoic crust [Durrheim and Mooney, 1994;Christensen and Mooney, 1995]. The mantle beneath the ocean and Tecton domains is characterized by a typical Phanerozoic composition, whereas the Archon mantle composition displays the following stratification: Archean from the Moho to 150 km depth and Phanerozoic from 150 km to the base of the thermal lithosphere (Table 1) sition, whereas the southern half is representative of an Archon domain [Afonso et al, 2008a;Griffin et al, 2009]. Since we are particularly interested in the effects of sub-Moho features, we assign the same crustal structure for the two continental domains (Figure 6).…”

“…Potential mechanisms include a rapid temperature increase , a change in seismic anisotropy Yuan et al, 2011], a low-velocity metasomatic layer [Chen et al, 2009;Griffin et al, 2009;Wölbern et al, 2012], and variations in water content [Karato, 2012]. Regardless of this ambiguity, the shallow negative energy is spatially correlated with the thermally perturbed lithosphere observed beneath the CRM (Figure 7a) and suggests that these features may be related.…”

“…Furthermore, a sub-grid of 25 MT sites in the south-eastern part of South Australia covers the transition from the Proterozoic to the Phanerozoic. Geochemically, the transition results in a thinning of refractory, iron poor sub-continental lithosphere (Griffin et al, 2009). Electrical laboratory measurements of main mantle constituting minerals suggest an increase in conductivity due to rehydration and fertilisation processes (Jones et al, 2009a).…”
