Fig. 8
Chrome spinel discrimination diagrams Mg/(Mg + Fe2) vs. Cr/(Cr + Al), showing the suggested field of provenance after Pober and Faupl (1988). Plots are shown for individual age intervals with samples grouped in different Gosau basins (Gießhübl, Glinzendorf, Grünbach and Slovakian Gosau basin). Pie charts illustrate the percentage of samples plotting in harzburgite (H) or lherzolite (H) provenance field. Plotted data from Online Resource 4
