In this study, the relationships between the physical and mechanical properties of
metamorphic rocks have been investigated based on data that were collected from
previous studies. The data for the physical and mechanical properties of metamorphic
rocks such as (Density, Young’s modulus, Uniaxial Compressive Strength (UCS),
Porosity, Tensile strength, Specific Gravity) for some types of metamorphic rocks (
Gneiss, Schist, Phyllite , Slate , Marble, Amphibolite, Hornfels and Quartzite) were
collected from previous studies. The statistical analysis has been investigated in order to
find the valuable relationships between physical and mechanical properties of the
studied rock.. The results revealed linear relationships between those properties. Based
on the coefficient of determination (R 2 ), the best linear correlations were obtained
between Young’s modulus and Porosity with R 2 of 0.86 whereas, the weak relationship
was found between UCS and Specific Gravity of R 2 =0.22. This indicates that there is not
a direct relationship between UCS and specific gravity.
