Appendix: Position of lithological profiles 
Distances are in railway kilometres, from N to S. These distances are keyed to railway km post 3.8 (= 3800 m). Railway km post 3.7 is at 3702,30 m and railway km post 3.6 is at 3603,48 m. 
Profile A - B to L - K: This is a continuous profile, consisting of four (“sub”-)profiles (A, B, L, K), of which the top part is referred to as profile A, and the bottom part as profile K. The top of profile A (top of sequence A826) reaches the base of the outcrop at 3603.98m, the top of profile L (base of sequence L300) reaches the base of the outcrop at 3623.65m, the base of profile L (base of sequence L200) reaches the base of the outcrop at 3641.9m and the base of profile K (base of sequence K89) reaches the base of the outcrop at 3650.29m. This combined profile contains profiles III-N (in profile A) and II-N (in profile L - K).
Profile C to D: This is a continuous profile, of which the top part is referred to as profile C, and the bottom part as profile D. The top of profile C (top of sequence C463) reaches the base of the outcrop at 3656.3m, and the base of profile D (base of sequence D295) reaches the base of the outcrop at 3682.8m. The stratigraphically highest convolute sandstone bed (basal part of sequence C429) reaches the base of the outcrop at 3665.5m. This profile contains profile I-N.
Profile J to F: This is a continuous profile, of which the top part is referred to as profile F, and the bottom part as profile J. The top of sequence F201 of profile F reaches the base of the outcrop at 3726.3m. Profile J contains profile I-S and profile F contains profile II-S.
Profile G to H: This is a continuous profile, separated by a fault from profile F, of which the top part is referred to as profile H, and the bottom part as profile G. Sequence G300 of profile G is juxtaposed against sequence F246 of profile F by a fault. The base of profile G (base of sequence G300) reaches the base of the outcrop at 3739.3m. The base of profile H (base of sequence H34, forming the limit between profiles G and H) reaches the base of the outcrop at 3757.5m. The top of sequence H219 of profile H (“sequence V”) reaches the base of the outcrop at 3771m. The top part of profile G contains profile III-S.
