Caracterización petrofísica de areniscas del Eoceno Medio–Superior del Pirineo Occidental

Abstract

In this work we have studied six varieties of Tertiary sandstone from the Pyrenees, they are all litharenites with medium grain size between 0,1 a 0,25 mm and porosity between 0,4 - 4%. Some petrographical and physical parameters (Mineralogical composition, absorption, free porosity, apparent density) and mechanical properties (compression and flexion strength resistance ) have been studied in order to establish a relation between them. The statistic study has showed the correlation between compression strength resistance and petrographical parameters. The content in cement has resulted to give the best correlation with mechanical properties
