... Solid-state flow during metamorphism was studied in a 300-km 2 exposure where Elba Quartzite forms the upper part of an autochthon and is overlain by two major allochthonous sheets. The quartzite is very locally thrown into north-verging recumbent folds, the largest having a wavelength of 1 km...

... described from Elba ( Collettini et al., 2009 ). The striking difference in the investigated process and the process described from Elba is that on Serifos, the talc formation was not triggered by an infiltrating Si-rich fluid but by the fluid-assisted reaction of the quartzite boudins and the dolomite...
