Interpretace petrografických a porozitních charakteristik pískovců s využitím metody CDA (Compositional Data Analysis)

摘要

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