Abstract

In order to understand the reason(s) why a specific stratigraphical horizon is used for cave development the AA. sampled 18 inception horizons of 6 cave systems as well as the surrounding rock mass. This paper only presents and discusses the results of the measurements of the primary rock permeability. The results indicate that the initial permeability contrast is not sufficient to explain alone the concentration of karst development along inception horizons. However, it is noticed that 3 types of inception horizons can be distinguished: type 1, where cave inception took place within the inception horizon and where the permeability of the inception horizon was slightly higher than that of the surrounding rock mass; type 2, where inception took place at the interface between the inception horizon and the surrounding rock mass, and where the permeability of the inception horizon is slightly lower than the surrounding rock mass; type 3, where the cave development took place along bedding plane fractures
