Compositions of the two generations of tourmalines from pelagic metasediments of the Bôrka Nappe, locality Dobšiná–Stirn, sample OS-07-147 (nomenclature of tourmalines according to Henry et al. 2011): a different composition of two generations of tourmalines in the diagram Ca/(Ca + Na) at X site vs. Fe/(Fe + Mg) at Y site; b different composition of two tourmaline generations in the diagram Al apfu vs. Fe/(Fe + Mg) at Y site: c Ca–Fe(tot)–Mg diagram with the numbered fields corresponding to the following rock types (Henry and Guidotti 1985): (1) Li-rich granitoid pegmatites and aplites, (2) Li-poor granitoids and associated pegmatites and aplites, (3) Ca-rich metapelites and calc-silicate rocks, (4) Ca-poor metapelites and quartz-tourmaline rocks, (5) Metacarbonates, and (6) metaultramafics (for chemical analyses see Online resource 5)
