It is nearly impossible to break or snap. If there is one thing that prevents granite from being ideal as a headstone marker, it’s the painted lettering. Still, the headstone will last for centuries before ...

Due to the different thermal expansion coefficients of minerals in granite, uneven expansion occurred under high temperatures; thus, cracks appeared on the surface of the granite at 800 °C and 1000 °C (Fig. 1), and cracks formed in the granite at 1000 °C were clearly more abundant and larger than those … See more Under a light microscope at 20 × magnification, the structures of the specimens and minerals observed after high-temperature treatment at 300 °C (Fig. 2a–d) did not change. At 400 °C and 500 °C (Fig. 2e, f), … See more As shown in Fig. 4, before a temperature of 500 °C was reached, the longitudinal wave velocity decreased linearly with increasing temperatures, and the wave velocity decreased by 46.1% at 500 °C. At 600 °C, the velocity … See more We defined the mass loss rate \eta_{{_{m} }}, volume growth rate \eta_{V}, and density reduction rate \eta_{\rho }as follows: In these formulas, m1, V1, and ρ1 are the mass, volume, and density of the original rock … See more As shown in Fig. 6, as temperatures increase, the stress–strain curve of granite becomes more gradual at 100 °C and the compaction stage … See more WebJul 18, 2024 · Our drilling starts in d-vein material and goes down 300m.
