- •
Diametral compression tests with acoustic emission and petrographic analysis.
- •
Pre-peak microcracking in both rocks is distributed in the central loading plane.
- •
Microcracks initiate through quartz in monzogranite releasing high-level energy.
- •
Cracks follow cleavage planes in marble releasing low-level energy.
