Rock types and structures of Valscura: a: D3 folds bending D2 axial planes in migmatitic paragneisses (coin for scale); b: D2 fold hinges transposed into S2 foliation planes. Centimetre-thick lamprophyre with unfoliated chilled margins crosscut S2 (camera cap for scale); c: spessartite dyke with not foliated to slightly foliated chilled margin intersecting D3 folds in migmatitic paragneisses (coin for scale); d: leuco-appinite vein into an appinite dyke; primary igneous minerals are locally replaced by aggregates of epidote and chlorite (yellowish in picture). Millimetre-sized D4 mineralised tensional veins are arranged along the leuco-appinite vein (camera cap for scale); e: D4 mylonitic foliations supported by chlorite and minor biotite interrupting and displacing to the right S1+2 foliation planes (compass for scale); f: spessartite dyke intruding fine-grained biotite-bearing granite. D4 foliation is pervasive along lamprophyre dyke walls (camera cap for scale).
