Higher relative humidity inside the tafone plays a key role in tafone growth. Orientations of tafoni help to keep a higher relative humidity inside the tafoni. Chemical and mineral analysis shows that tafone was formed by chemical weathering. Extra Na and clay mineral denote that tafone growth was caused by physical weathering.
