Foliation roche

http://geologyscience.com/rocks/metamorphic-rocks/gneiss/ La foliation (du latin folium, feuille), est une structuration en plans distincts des roches métamorphiques. La structure est marquée par l'orientation préférentielle de minéraux visibles à l'œil nu — le plus souvent les micas — et aussi en microscopie optique. Contrairement à la schistosité affectant ces mêmes roches métamorphiques, le caractère spécifique de la foliation est la d…
