a Map of energy dispersive X-ray (EDX) spectra in garnet micaschist. Spectra for garnet porphyroblasts are labelled in a generic way by Fe, Mg, Mn, and Ca contents in normalised element wt%. Bt biotite, Grt garnet. Locations of analytical profiles and traces of foliations S1i by aligned elongated quartz (Qtz) inclusions and opaques, and S2 by mica plates are marked. Numbers are EMP analyses along profiles. b, c Zonations in micaschist garnet including almandine (Alm-50%, due to scale), pyrope (Prp), grossular (Grs) and spessartine (Sps) components (in mole%). Numbers are selected garnet analyses used for geothermobarometry. The profiles are labelled from the cores (c) to the rims (r) of garnet. d Garnet zonations in XMg-XCa coordinates. Arrows indicate core-to-rim (c, r) zonation trends from single garnet profiles. Numbers are selected garnet analyses for geothermobarometry. Note different Ca bulk rock compositions in wt% from Table 1. The garnet XMg-XCa zonations refer to the semiquantitative pressure–temperature trends A (heating-compression), B (heating-decompression) and C (isothermal decompression), as outlined in Spear (1993). e Mineral chemistry and zonations of Ca-amphibole in metabasite samples, nomenclature according to Leake et al. (1997). f Ca-amphibole zonations in IVAl vs VIAl coordinates, with relative P–T trend. c1, c2 cores, r1, r2 rims of amphiboles
