Sandstones petrographic and porosity parameters interpretation with use of Compositional Data Analysis

Abstract

In this paper is tested a possibility of implementation of a statistical method: Compositional Data Analysis in the interpretation of porosity measurement data and petrographic data of rocks. The sampled rocks were Polish building sandstones divided into 4 groups related to a geological region or a stratigraphical position. Porosity analysis performed for 35 sandstone samples include measurement of effective porosity, dynamic porosity as well as the pore area parameters. The results of the analyses were interpreted with the use of CDA. This same procedure was used when the porosity date were correlated to mineral composition of the sandstones.
