WebAug 9, 2024 · They also have distinct cleavage planes and fine parallel lines called striations. Examples of plagioclase are albite, labradorite, and oligoclase. In geology, a striation is a groove, created by a geological process, on the surface of a rock or a mineral. In structural geology, striations are linear furrows, or linear marks, generated from fault movement. The striation's direction reveals the movement direction in the fault plane.
