Nappes in the Molo-Kara-Dzhilga – Aksai interfluve (for location see Fig. 1). Symbols follow Fig. 4. Most stratigraphic indices on the map coincide with those given in Fig. 2. Encircled digits are nappe-limiting faults (see Fig. 5). C? – Carboniferous(?) deposits of the Saly-Mula unit [26] contributing to the structure of the Muzkol nappe; T3 – sandstones and schists of the Kara-Istyk series making up the tectonic outliers of the South Pshart nappe (see Figs. 1, 2, and 5).

... and Triassic, respectively; Rutte et al. 2017 b ; Schmidt et al. 2011 ). This outcome may explain the absence of the low-velocity zones coinciding with the domes in the Central Pamir. Instead, the location of the Central and Northern Pamir gneiss domes (Muzkol, Sarez, and Kurgovad) coincide with elongated...
