The texture described is phaneritic, meaning the mineral grains are coarse enough to be seen without magnification and of roughly equal size. Aphanitic textures have grains too small to be seen without magnification, pegmatitic textures have abnormally large grains, and porphyritic textures have both large and small grains.
