A texture seen in granites and pegmatites and characterized by a coarse intergrowth of quartz and alkali feldspar on a scale of tens of microns. The texture can be very coarse when developed in certain pegmatites, the intergrowths developing on a scale of several millimetres, and is easily seen in hand specimen, looking rather like cuneiform (i.e. wedge-shaped) writing. When developed on a microscopic scale, graphic texture is termed granophyric texture.
