Relationship between Textural and Mineralogical Properties of Crystalline Igneous Rocks Using Textural Quantification by Image Analysis

The mineralogical and textural characteristics of rock materials have an important influence on physico-mechanical properties. The effects of some textural characteristics like grain size (Brace, 1961), grain shape (Cox and Budhu, 2008), grain surface (Diepenbroek et al., 1992), grain size distribution (Gurkan Ozgurel and Vipulanandan, 2005), and grains interlocking (Hoek, 1965) on physico-mechanical behavior of rock materials has always been emphasized. On the other hand, it has been found that textural properties are originally controlled by the mineralogy and chemistry of rock materials (Locat et al., 1984). Knowing the textural, mineralogical and chemical properties of rock materials and understanding the governing relationships can help us predict the quantitative and qualitative behavior of rock materials. The aim of this study is to investigate the interrelationships among the various textural properties besides the relationship between the textural characteristics and the mineralogy and chemical composition.
