Short summary
This study shows that the weathering rates of limestone, determined from of an ancient eroded edifice, can exhibit highly non-Gaussian behavior. Moreover, the asymmetric long-tailed curve was found to have similar characteristics to those of rate distributions measured on microscopic regions of limestone surfaces in laboratory experiments. Such similar behavior could reflect analogous chemical and mechanical weathering mechanisms operating over a range of spatial and temporal scales.
