Figure 5. Photograph of a felsic rock composed of lens-shaped inclusions of older felsic rock. The inclusions are parallel, imparting a strong flow structure to the rock. Within the lenses, on the microscopic scale, plagioclase laths also show a strong flow structure parallel to the lengths of the lenses.
