Differences between the modes observed in spinel peridotite xenoliths and those predicted by experiment may result because the former are not simple residues, and have had components introduced after their original formation. 

Figure 8 Mg/(Mg + Fe) versus Mg/Si for (a) off-craton spinel peridotite xenoliths and (b) cratonic garnet and spinel peridotite xenoliths. Arrows mark the oceanic trend (Boyd, 1989, 1997) defined by abyssal peridotites. Also shown are various estimates for primitive upper mantle (polygons from Table 7).

The best characterized noncratonic, spinel peridotite xenoliths for PGEs are those from southeastern Australia (Handler and Bennett, 1999), the Massif Central, France (Lorand and Alard, 2001), Western USA (Morgan et al., 1981 Lee, 2002) and Vitim, Siberia (Pearson et al,...
