p.41: The Brunni Granite is a homogeneous leucocratic granite with characteristic large crystals of allanite/epidote and locally K-feldspar megacrysts. It is affected by a weak foliation of Alpine age, which becomes more intense towards the south (SCHALTEGGER et al.1991). It forms an intrusive complex together with the Düssi Diorite (δD) showing abundant magma mixing and mingling structures (GNOS 1988, RIESEN 1991).
