Fig. 9
Detrital tourmaline diagrams using the Fetot–Altot–Mg and Fetot–Ca–Mg triangle plots and provenance field suggested by Henry and Guidotti (1985). 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 from where the tourmalines are supposed to be derived are given below the plots according to the authors. Plotted data from Online Resource 5
