Table 2
Main mineral morphology features of granite.
| Mineral | Particle size (mm) | Particle structure | Crystal form | Cleavage | Mohs hardness |
| Biotite | 0.4–1.0 | Self-shaped flake structure, perfect cleavage | Flake | Perfect cleavage | 2.5 | Quartz | 0.2–1.5 | Aggregate distribution, noncleavage | Prismatic and granular | Noncleavage and conchoidal fracture | 7 | K-feldspar | 1.0–5.0 | Lattice double crystal structure and perthitic texture | Thick plate and short columnar | Two groups of cleavage | 6 | Plagioclase | 0.5–3.0 | Semi-self-shaped plate, cluster twin, and girdle structure | Plate | Two groups of cleavage | 6–6.5 |
