a Map of the southern Altaids, modified after ref. 19. b Regional geological map of the AMC in Chinese STO, modified after refs. 27,30. c Synthetic and schematic lithological profile, along the cross-section from north (top, A) to south (bottom, A’). d Field view of the Muzetekexie valley, modified after98; the dotted part of the line represents a more diffuse nature of this contact, and the studied unmetamorphosed basin is unconformably overlying the greenschist-unit. e Climbing ripples observed in sandstone outcrops. f Mud-crack preserved in sandstone crops. g Several cent-meters scale clasts in conglomerate outcrop.
