Since the ice single crystal is extremely anisotropic, such marked crystallographic textures lead to macroscopic anisotropy which must be taken into account in flow models. To describe the anisotropic behaviour of polar ice and the development of its crystallographic texture, “micro-macro” models are...
The emplacement of the Morcles microgranite was very shallow, as testified by the fine-grained subvolcanic textures of the groundmass. This feature is structurally coherent with the regime of extension that led to the contemporaneous formation of the nearby Salvan-Dorénaz basin over the AR poly...
From the overall petrostructural pattern, it is inferred that magmatic bodies of different petrographic nature and textures were emplaced within low grade country rocks. Palaeozoic in age, while these rocks were subjected to large scale, SE-NW subhorizontal shearing. The sense of shear is ...
