Graphic granite is found to some extents in almost all granitic pegmatites. It is a textural term and refers to the patterns of quartz appearing as ancient writings. The texture itself is a hallmark of granitic pegmatites. It is mostly composed of skeletal habit quartz crystal rods suspended in feldspar matrix. Amazingly 90% of the quartz rods are connected (London in Pegmatites). Attached to the backside of this specimen are dark muscovite plates.
