Abstract

The aim of this work is to study the magmatic and structural evolution of the meta - granitoids exposed in a low strain domain of the Zillertal - Veneiger Core in the Tauern Window. At first, the relationship between the lithologies of the Variscan basement and the Alpine milonites and veins was analyzed. Granodiorite, Gabbros and Ultramafic Cumulates, Leucogranite dykes with magma mingling, Aplitic and Lamprophiric dykes and Epidot + Garnet veins show, on the field, particular relations that permit us to reconstruct a relative chronology of the magmatic evolution. Milonites, Quartz + Calcite + Biotite veins and Epidote + Chlorite structures are the evidence of the Alpine deformation and the second part of the evolution of the Variscan basement. In a second moment was characterize the relationship between the localization of the strain and the pre-existent structures, like compositional and structural discontinuities. The last part of the work concerns the analysis of the structural data detected on the field constraining a σ1 principal stress direction during the Alpine event. A geologic map was prepared after the analyses of the aerial photos and integrated with the field work. This study is based only on field evidences, geological and structural survey techniques.
