Their stratigraphic ages and the compositions. Furthermore, strength as wellĪs the porosity of sandstones shows distinct differences considering Similar petrophysical properties are discernible for each type Water uptake properties, which were obtained by linear regressionĪnalysis. All sandstone groupsĭiffer with respect to the pore space and strength data, as well as Lithoclasts can also show considerable alteration. However, in the last two groups the feldspar and Quartzites, highly mature, showing a primary porosity of 40% but withĮarly clay infiltration, iii) sublitharenites-lithic arenites exhibitingĪ lower primary porosity, higher cementation with quartz and Fe-oxidesįerritic and iv) sublitharenites-lithic arenites with a higher content I) quartzites, highly mature with a primary porosity of about 40%, ii) In general, the sandstones can be grouped as follows: Samples investigated mainly originate from the Triassic GermanĮpicontinental basin, arkoses and feldspar-arenites are Valuable information to predict the strength properties. Intergranular volume, cementation and grain contact, can also provide Petrophysical properties of a building stone. Porosity evolution during diagenesis is a very important control on the Specific sandstone types, principle component analysis, cluster analysisĪnd factor analysis were applied. Similarities between individual sandstones or to define groups of Swelling and salt loading tests were also included. The sandstones wereĬlassified into three different pore size distributions and evaluated Porosity, water uptake as well as the strength. Linear regression of the basic petrophysical properties of density, Methods were used to test for normal distributions and calculating the Textural maturity, grain contact respectively contact thickness, type ofĬement, degree of alteration and the intergranular volume. Particular attention was paid to evaluating the compositional and Mineralogical composition and fabric characteristics were determinedįrom detailed thin section analyses and descriptions in the literature. Historical and presently mined natural sandstones in Germany and onesĭescribed worldwide were included in the statistical approach. The aim of this study is toĭevelop constraints on the material behaviour and especially on the Petrophysical properties of sandstones, a large dataset could beĬompiled for the statistical analyses. Since the literature alreadyĬontains a large volume of data concerning the petrographical and Sufficiently large dataset, a systematic approach to predicting the Stone industry, an understanding of the material behaviour of thisĬonstruction material is very important. From the viewpoint of conservation and the natural
The different applications for these stones have led to an Sandstones are a popular natural stone due to their wide occurrence andĪvailability.
