“…A deformation temperature difference of >150 °C between the dyke and the vein is supported by the quartz pole figures that suggest rhombohedral <a> slip together with basal <a> slip and subordinated prism <a> slip (Passchier and Trouw, 2005) for deformation of the vein. This reconstruction unveils that the fast transition into the brittle domain, still involves ductile deformation, in contrast with what is expected for quickly cooling upper crustal granitic plutons (Caggianelli et al, 2000;Moyen et al, 2003;de Saint-Blanquat et al, 2006;Gonzáles Guillot et al, 2018;Liu et al, 2020).…”
