a Quartzitic gneisses containing garnet poikiloblasts with D1 internal foliation and D2-postdeformative mineral growth of hornblende aggregates retrogressed to biotite. Photo taken from Hoinkes et al. (2010). b Large-scale (F2) and small-scale open (F3) folds at study area G. Note, different plunge directions between F2 and F3. c D2-postdeformative kyanite-bearing quartz veins (study area G). d Non-cylindrical intrafolial fold structure F2 within metabasic gneisses at study area H. e F3-open folds at study area H. f M-shape of intrafolial folds F2 within garnet-bearing gneisses at study area J. g D2-postdeformative mineral growth of garnet rims at the fold hinges of F2 folds (detail in f). h Large-scale quartz vein formed due to NW–SE-directed extension (study area I)
