AB The purpose of this study is to determine the influence of anisotropy on hydrical properties of brecciateddolostones (BD). The present investigation involving BD has revealed, on the one hand, at meso-scale, fourtypes of fractures. On the other hand, mercury intrusion porosimetry (MIP) has delimited two main porousfamilies: pores of rock matrix and micro-fracture systems. Capillary transport and permeability tests wereperformed on four types of BD in order to establish the correlation between these parameters and theporous-fracture systems. The results show strong anisotropy in capillary absorption measured on prismaticsamples in their three orthogonal directions. At the same time, our study has demonstrated that permeabilitycorrelates with both capillary absorption, as well as fracture density. Finally, the porous system of BD can bedescribed in two ways: as a tri-continuum medium that consists of pores belonging to the pore matrix,fractures and cavities or as a dual-porosity model embedding fractures and vein intercrystalline porosities
