Fig. 6
Garnet chemistry variations displayed as triangle plots for detrital garnets proposed by different authors (data from Online Resource 3). Left column almandine (Alm) + spessartine (Sps) − pyrope (Prp) − grossular (Grs) triangle plot after Preston et al. (2002). Middle column the same after Moore et al. (2003). Right column almandine − pyrope − spessartine triangle plot after Méres (2008). Plots are shown for individual age intervals with samples grouped in different Gosau basins (Gießhübl, Glinzendorf, Grünbach and Slovakian Gosau basin). Fields for interpreted provenance (lithologies or metamorphic facies) from where the garnets are supposed to be derived are given below the plots according to the authors. Pie charts illustrate the percentage of samples plotting in the different fields of provenance (gray scale indicates the metamorphic character of the provenance)
