WebPHANERITIC: 1/16 mm to 3 cm: Average size of crystal-grains is more or less uniform and the average grain size is in the range, 1/16 mm to 3 cm. For instance, in a granite typically 85% or more of the crystals might be close to 1 cm in size. There may be some smaller grains and some larger grains, but not many of each. WebPhaneritic ( phaner = visible) textures are typical of intrusive igneous rocks, these rocks crystallized slowly below Earth’s surface.
