Porosity and connectivity of the porous network of a sheared granite in green schist facies, are showed by a capillary test under CT X-ray. A strong correlation is pointed out between mineral phases, strain (dissolution- crystallization, shearing), porosity and connectivity of the network. Porosity evolves between 5% in K-feldspars and 0.1% in quartz and muscovite layer. Transfer properties are higher of one order of magnitude in the shear-plane than in the perpendicular direction.
