"Chisel marks" on columnar joint face
The sides of any columns in columnar jointing do not form a single uniform fracture, rather they grow incrementally. Each subhorizontal fracture increment, known as a "chisel mark," has its own fracture surface markings that indicate the direction of growth of that fracture. Most fractures...
