Alternating eclogitic amphibolites, mica schists and orthogneisses in the Schobergruppe to the south of the Tauern Window suffered a post-Upper-Ordovician progressive deformation D₁-D₂ which produced parallel planar-linear structures in all the rocks. Zoned garnets, preferentially oriented zoned clinopyroxenes (Jd 35–42%) and albite (An 7–9%) give evidence of high-pressure metamorphism (550–650°C, 14–16 kbar) of the metabasites. Ca-amphiboles crystallized during subsequent decompression. In a kyanite-staurolite-garnet mica schist 300 metres below the metabasites, garnet-bearing assemblages grew synchronous with the development of foliations S₁ and S₂. Garnets are zoned with increasing X_Mg and decreasing-increasing-redecreasing X_Ca from cores to rims. Albitic plagioclase (An 1–3%) and micas are enclosed in garnet cores and rims, are in contact with garnet, and occur with garnet in microlithons. When these minerals are used for geothermobarometry, a prograde P-T evolution (460 to 680°C with coeval pressure variations which reach high-pressure conditions can be estimated. This suggests that garnet-plagioclase geobarometry with albitic plagioclase works in the relevant P-T field. Similar garnet zonation trends and a similarly shaped P-T path from mica schists of an adjacent region with late-Variscan cooling ages, points to an early-Variscan age of the syn-D₁-D₂ high-pressure and subsequent amphibolite-facies metamorphism.
