Field photographs. Italic numbers correspond to tunnel meter (TM) where the images were taken. This is also valid for subsequent figures with field photographs or photomicrographs and will no longer be mentioned. a Contact between Tremola series in the SE and Prato series in the NW, hammer for scale. b Folded and sigmoidal quartz aggregates indicating top-to-south shear sense (upward movement of the northern block) in the Prato series, pencil for scale. c Contact between Prato series in the SE and Rotondo granite in the NW. The Rotondo granite consists at the contact to the Prato series of an approximately 5 m wide zone of highly deformed granite. Pencil for scale. d Contact between the porphyritic variety of the Rotondo granite (RG2) in the SE and the equigranular variety of the Rotondo granite (RG1) in the NW. Note that the RG2 is relatively strongly sheared at the contact and that the RG2 further to the SE is not as dark as in this photograph. Hammer for scale
