Their origin is assigned to the phenomena of mechanical and chemical erosion due to the almost permanent presence of rainwater or runoff.
Stagnant water contained in the cavities has a very low pH and therefore has a corrosive action. By this extremely slow process, several neighboring cups may meet in the end: they became "coalescent cups".


Free access.
