Abstract

Microtextural features influence the petrophysical and mechanical properties of rocks, including the elastic properties and cracking processes under axial loads. Volcanic rocks with varying microtextural characteristics and compositions were evaluated to assess the effect of the main constituents' mineralogical, petrographic and micro-structural features on the petrophysical properties, elastic properties and strength. Furthermore, detailed analyses were also used to understand the cracking processes under axial loads. The analyses of the cracking processes were completed on thin sections obtained from the mechanically tested specimens.
