Fig. 5. Trace-element and O-isotope compositions of amphibolite from the Waroonga greenstone belt.

Fig. 5

a Normal mid-ocean ridge basalts (N-MORB) normalized incompatible trace-element patterns of the garnet amphibolite, showing the distinctive differences in rare Earth elements (REE), large ion lithophile elements (LILE), Th and, in particular, high field strength elements (HFSE), in the EA group. b Mantle-normalised incompatible trace-element patterns of garnet in UA and EA. Compared with UA, EA garnets show strong enrichments in REE, without enrichment in Nb (only two analyses, both shown as traces, with Nb above detection) or Th. c Secondary ion mass spectrometer (SIMS) δ18O analyses across garnet grains of sample 214208 and 155899. The grey bar shows the mantle δ18O range44.
