Neoarchean (ca. 2680 Ma) granites displaying a well-defined planar fabric due to the injection of tonalite to monzogranite sheets aligned parallel to the magmatic foliation, which is defined by aligned euhedral feldspars. No effect of important solid-state deformation is visible at outcrop-scale. The base of photo is about 1 meter.
