chlorite_breccia

The chloritic breccia zone is exposed as a green, easily weathering planar zone containing angular clasts of a variety of sizes and running below and parallel to the detachment fault.
The compositional layering of the mylonitic gneiss is poorly preserved but present (e.g., white band running across the center of the photo).
