Abstract
The Furgg zone consists of three units. The first one, the lower Furgg zone, is made of gneiss, the second one, the middle Furgg zone, is a Mesozoic series crosscut by mafic dikes and the third one, the upper Furgg zone, consists of gneiss and meta-arkose hosting numerous boudins of mafic rocks. This last unit has been assigned a Middle Jurassic age. The studied area is strongly affected by backfolding. These folds are associated to the classical E-W dextral shear zone. The value of the direction of shear is around 280°/40°. This interpretation is compatible with the reorientation of the older structures.
