The Miocene Tokuwa granodiorite is classified into ilmenite-series and magnetite-series granitoids. Dimensional preferred orientation of plagioclase in the texture of two-series granitoids is characterized by lie on the horizontal plane. Lattice preferred orientation of quartz in the same granitoids shows three types as following 1) diffuse pattern, 2)weakly orientation and 3) strong orientation.The lattice preferred orientation in the texture of magnetite-series shows mainly to diffuse pattern. The strong orientation pattern shows only the texture of ilmenite-series granitoids. The preferred orientation of plagioclase in the granodiorite was formed by molecule convection and the lattice preferred orientation and growth of quartz also might be formed by molecule convection during cooling procss of the granidiorite maga.

中新世德轮花岗闪长岩分为钛铁矿系列和磁铁矿系列花岗岩。二系花岗岩结构中斜长石的尺寸择优取向特征是位于水平面上。同一花岗岩中石英的晶格择优取向表现为以下三种类型：1）扩散型、2）弱取向型和3）强取向型。磁铁矿系结构中的晶格择优取向主要表现为扩散型。强取向图案仅显示钛铁矿系列花岗岩的结构。花岗闪长岩中斜长石的择优取向是由分子对流形成的，石英的晶格择优取向和生长也可能是花岗闪长岩冷却过程中的分子对流形成的。
