Hydraulic behaviour of the rock matrix at the calcareous Campos site coastal aquifer (Majorca, Spain)

In the framework of a wider European study of saline intrusions in coastal environments, the hydraulic behaviour of the rock matrix at the calcareous Campos site coastal aquifer (Majorca) has been characterized. This characterization is performed on rock cores in laboratory; its main objective is the relation between the hydraulic properties of the rock matrix and the rock forming components of petrophysical significance, specially the pore space structure. The anisotropy and heterogeneity is previously analyzed. The real and apparent density, effective and non-effective porosity, range of pore throat size, free and forced water absorption, water desorption, coefficient of capillarity and water vapour permeability have been evaluated. Seven different types of porosity according textural considerations have been established
