Schmidt nets of structural elements, lower hemisphere. a Distribution of Zapport foliations on a great circle points to main fold axis orientation of the Leis Phase (FA 054/19). This is parallel to measured fold axes shown in (d). b Poles of main foliation (Leis Phase). The pole of the great circle dipping shallowly to the ENE suggests a fold axis of the younger D3 (Carassino Phase, FA 074/08). c Measured fold axes related to the Zapport Phase. d Measured fold axes related to the Leis Phase. e Mineral lineations defined by amphibole and feldspar in massive K-feldspar augengneiss, related to the Zapport Phase. f Stretching lineation of the Leis Phase, defined by chlorite, white mica and quartz
