Regional distribution of PBT axes compared with foliation and fold axes and stretching lineation data a Lower-hemisphere equal-area projection plots of structural data measured in the study area (cf. Fig. 3g, h). b Plot of poles to foliation, fold axes, stretching and intersection lineations, with the eigenvectors calculated for the poles to foliation indicated as yellow triangles. Data are plotted separately for the western (Aiguilles Rouges/Mont Blanc), central (“Rawil Depression”) and eastern (Gemmi–Oeschinensee) parts of the Rawil Depression
