Armor (geology)
Harnisch is an old miner's expression for a trace of movement on a fault surface, which was created by the fact that rocks sliding against each other smoothed the surface. In the process, embedded harder rock components leave scratch marks on the sliding surface in the direction of the displacement. They are an indication of movements and their direction in the geological past. The parallel stripes often have fine tear-off edges. Based on these edges, the relative movement of the rock pacts can be reconstructed.
In cases where the sliding surface has been polished during movement, it is also referred to as a mirror armor .
