Three major sandstone petrofacies have been defined on the basis of texture and detrital compositions, diagenetic features, and pore space properties (i.e., pore abundance and type).
The two sandstone petrofacies, highly compacted, ductile lithic-rich, very fine-grained sandstones, and tightly calcite-cemented sandstones may create permeability barriers or baffles embedded in porous reservoir sandstones.

This paper addresses sand petrofacies formed during the Middle Aragonian (14.2Ma) at the Somosaguas palaeontological site (Madrid Basin), the evolution of their source area (Spanish Central System) and the climate that prevailed over the middle Miocene in this area.

Thus, petrofacies are useful for analyzing depositional sequences and, consequently, the organization and develop of the clastic sedimentary record of the basin filling.
