Schematic block diagram of intermingling zone at the Moho. It visualizes the generation of the four main lithologies (para- and orthogneisses, migmatites and banded amphibolites) during the cratonization of a subduction–accretion complex (Zurbriggen 2017). Abbreviations: 1: first production step of banded amphibolites by intermingling, 2: second production step of banded amphibolites by shearing, O: Ötztal Nappe, S: Silvretta Nappe, G: Gotthard Nappe, C: Strona-Ceneri Zone, A: Aar Massif. The units are located according to their individual lithological characteristics. For further explanations see text
