Field photographs from the eastern part of the RFZ2 above the Rezli glacier lake. The locations of the photographs are indicated on Figs. 3 and 6. a Conjugate brittle normal faults displace a layer rich in phosphate nodules in the Garschella Fm. Width of view ~10 m. b Tectonic lens of Seewen limestone adjacent to the main fault plane. Many anastomosing shear zones developed in the Seewen marls. Hammer for scale. c Angular blocks of Klimsenhorn Fm incorporated into the fault zone. Hammer for scale. d Massive, up to 1 m wide calcite veins in the Wildstrubel Fm. Hammer for scale. e Main fault plane associated with coarse angular breccia in the Wildstrubel Fm. Width of view ~10 m. f Close-up from e. Breccia of angular to rounded clasts of Wildstrubel Fm cemented by blocky, white calcite. Hammer for scale
