A new theory is presented for the origin of myrmekite which is believed to be formed by the incorporation of recrystallizing quartz in growing albite. The albite is exsolved from orthoclase. The rod-like form of the quartz is explained. Drescher-Kaden's work (1948) is discussed. It is believed that myrmekite can be of assistance in elucidating the complex history of formation of granites.
