A big, complex fold crosscut by two transversal valleys (San Nicolò V. and Contrin V.) dips under the Marmolada massif. Here’s the section in between with the central-upper part removed by erosion. The axial surface – striking ENE-WSW – is approximately normal to the picture’s plane and runs trough the salt diapir in the center….

A big, complex fold crosscut by two transversal valleys (San Nicolò V. and Contrin V.) dips under the Marmolada massif. Here’s the section in between with the central-upper part removed by erosion. The axial surface – striking ENE-WSW – is approximately normal to the picture’s plane and runs trough the salt diapir in the center. Passo San Nicolò ridge, connecting Sas de Roces and Col Ombert on the opposite flanks of this diapiric anticline, is the hinge line of a perpendicular fold, sub-parallel to the Marmolada overthrust in background.
