preferred orientation The alignment of inequidimensional mineral grains in a rock to define a two-dimensional, planar fabric or a three-dimensional, linear fabric. Alignment may be caused by deformation accompanying metamorphism, flow of crystal-laden magma, settling of crystals in a magma, or settling of flaky minerals in water.
