Basic physical and mechanical parameters of the BHT basalt and BS granite samples.
| | Rock type | Density (g/cm3) | P-wave velocity (m/s) | Young’s modulus (GPa) | Poisson’s ratio (μ) | Tensile strength (MPa) | Grain size (μm) |
| | BHT basalt | 2.95 | 5650 ± 150 | 55∼60 | 0.22 | 18.4 | 50∼150 | | BS granite | 2.69 | 5100 ± 120 | 50∼54 | 0.27 | 5.06 | 500∼1500 |
