Thin sections showing (A) dominant top-to-the-SSW senses of shear (SC structures) at the upper half of the thin section and dominant top-to-the-NNE senses of shear at the lower half interpreted as the SSW ending of a microscopic lens, (B and C) symmetric MPD lenses around resistant feldspars, (D) detail of a late semi-brittle normal fracture crosscutting the whole thin section, (E) MPD domino-type bookshelf feldspars indicating parallel but opposite senses of shear. The thin section consists of parallel bands indicating alternating top-NNE and top-SSW shear senses. In each parallel band, bookshelf feldspars are consistent with the flow revealed by quartz fabrics, pressure shadows and shear bands, (F) outcrop showing centimetre-scale MPD lenses (Saint Martin area). Picture E refers to the Figure 1 where the location of the photos is shown (orange circle).
