Abstract
The geotechnical properties of any rock are affected by its mineral composition, alteration, weathering, and micro structures of the rock. Limited experimental validation of the existing correlation between petrographical and physico-mechanical properties of rocks inhibits practical use of petrographical thin sections to determine the strength properties. In this study, the extensive analysis of thin sections shows that the quartz has a positive correlation with UCS in the rock samples while presence of K-feldspar, Plagioclase and Biotite shows negative correlation with UCS of different rock types.
