Outcrop and landscape scale structures. a Penetrative S2 foliation with flattened quartz lenses crenulated by late foliation S3; locally, minor shear planes C oblique on S3 indicates top-NE shear sense; Battuira (44.4274 × 7.2128), Val Grana Upper Liassic-Dogger(?) turbiditic limestones. b Tight crenulation schistosity (S3) entirely transposing bedding and earlier foliation (S2) in the Queyras calcschists beneath the Pelvo d’Elva backthrust; Ussolo (44.4910 × 7.0260). c Campomolino open anticline (F3) seen from the crest north of Punta Castellar (44.4067 × 7.1837); Val Grana unit, Sinemurian bedded limestones and breccias topped by the Pliensbachian Bercia limestones. d Close-up of carbonate breccias to the SW of (c); F3 folds (deforming a thin breccia bed and minor calcite veins) in foliated marbles showing lenticular texture and tilted, flattened dolostone pebbles; Val Grana Middle-Upper Liassic member west of Punta Castellar above San Magno (44.4041 × 7.1771). e Western (normal) limb of the Monte Bettone F3 anticline from the Vallone d’Elva (hazardous!) road; a minor parasitic anticlinal fold is seen below the major hinge; Norian bedded dolostones of Val Grana unit. f Detail of an oblique cleavage (S3) that exceptionally affects the dolostone beds, slightly oblique (N130E) with respect to the fold axis in map view (N160E); lowest Vallone d’Elva (44.4980 × 7.1010). g Tight similar folds (F2) deforming S0-1 with tilted axial plane due to later major folding (F3, not shown) in Upper Jurassic meta-cherts of the Queyras klippe, eastern cliffs of Monte Plum (44.4297 × 7.2303). h Folding of an early metamorphic foliation by superimposed recumbent F3 (?) folds; Anisian-Ladinian dolomitic limestones and argillites associated with cargneules west of Lottulo, Val Maira subunit (44.4940 × 7.2113)
