Quartz vein Schist in this outcrop, stress has caused a quartz vein to "break" into to small fragments while the mica schist was able to "flow" around the quartz fragments. Why did this occur? The mica plates in the schist could slide past each other while the solid quartz behaved in brittle manner. Schist can never be affected by tectonic stress while quartz always will. The quartz vein is older than the schist causing it to break more easily than the younger schist.
