The Barrios Formation is one of most characteristic lithostratigraphic units in the external parts of the Variscan orogen. It is constituted by continuous quartzarenites that can exceed a hundred meters in thickness. These rocks are present in almost all tectonic units within the Cantabrian Zone. The mineralogy determines its strength for most part of the unit, particularly for the beds made of quartzarenites. In this contribution, basic physical and mechanical properties are described in samples from six blocks, generally fresh, from which 64 cores have been tested. The properties determined are apparent density, open porosity, strength to uniaxial compression, tensional strength (brazilian testing), and elastic properties using ultrasonic testing.
