Plot of analysed wt% K2O (recalculated from % K in Table 2, error bars ±2 %, hardly visible on the plot) versus vol% 2M1 (error bars ±5 %) for all size fractions for which data is available (Table 1). The range of wt% K2O in representative muscovite analyses from the Innsbruck Quartz Phyllite in the immediate footwall is also given (9.39–10.6 wt% K2O; data from Piber and Tropper 2007), as well as a representative illite analysis (7.26 wt% K2O; Mineralogy Database of http://webmineral.com/). Data table for the plot is available in Online Resource 2
