Close-up of a deformed gneiss with swirling bands of dark grey and pale cream rock, curving into S-shaped loops, with scattered reddish-brown garnet clusters. — Migmatite 'sigmoid' in garnet-paragneiss Sophie Graul

Rock outcrop of dark grey amphibolite blocks cut by a network of pale granitic veins, some crossing the others, with a geological hammer lying across it for scale. — Metamorphic complex with amphibolite enclaves crossed by two generations of granitic veins Sophie Graul

Outcrop of dark grey amphibolite slabs separated and veined by pale cream and pink granitic rock, with a red-handled geological hammer at the bottom for scale. — Amphibolite enclaves crossed by two generations of granitic veins Sophie Graul

Pale pink vein folded into a tight zigzag of loops, crossing finely striped dark grey and reddish rock, with a red-handled geological hammer at the bottom for scale. — Ptygmatic fold crossing a mylonite, within a paragneiss. Sophie Graul

Close-up of a stretched dark patch of grainy black hornblende crystals, edged by sandy pink-beige granitic rock with dark streaks, the surface glinting with tiny reflections. — Close-up of hornblendes crystals in stretched amphibolite enclave Sophie Graul

Pinkish-beige granite boulder holding dark grey angular blocks of meta-gabbro, lying among rounded grey pebbles, with a red-handled geological hammer for scale. — Example of meta-gabbro/amphibolite enclaves in a granite vein (possible pegmatite texture). Sophie Graul
