Granites appear to be isotropic, which qualifies them as suitable crystalline host rocks for nuclear waste repository sites. However, despite their optical appearance, granites show a primary structural anisotropy (Bouchez, 1997) that evolved during emplacement and crystallization of the melt. We present the first results of a systematic study of felsic plutonites, i.e. the GAME project, which aims to lead to a better understanding of felsic plutonites as a geomaterial.
