a Geothermobarometry and P–T estimates from garnet micaschists. Crosses mark results from garnet-biotite (Grt-Bt) thermometers and GASP and GBMP barometers; HP—Holland and Powell (1998); Wu—Wu (2015). See text and Table 2 for details and combination of analyses. Arrow indicates P–T trend given by combination of data from samples RZ33 and RZ42. The aluminosilicates (And, Ky, Sill), cordierite-in (Cd +), muscovite-out (Ms −) and staurolite-in and -out (Sta + , Sta −) univariant lines are after Spear (1993). Bold crosses marks a general uncertainty of ± 50 °C and ± 1.0 kbar. b Geothermobarometry and P–T estimates (crosses) from amphibolitized eclogite (RZ24) and amphibolite (RZ37), by the Ca-amphibole equilibria geothermobarometer (ZS) by Zenk and Schulz (2004). Isopleths for jadeite (Jd10; Jd20; Jd40) content in clinopyroxene after (H) Holland (1980; 1983). A potential and questionable higher pressure stage indicated by decomposition of Na-rich clinopyroxene to symplectites is indicated
