Brittle deformation rocks
WebApr 12, 2024 · The electrical resistivity and elastic wave velocity of rocks are sensitive to the presence of both cracks and fluids, such that these physical properties are frequently used to investigate structural changes in the crust (e.g., Scholz et al. 1973; Nimiya et al. 2024; Minami et al. 2024).Laboratory experiments can monitor microcrack formation due to … WebThe brittle–ductile transition zone is characterized by a change in rock failure mode, at an approximate average depth of 10–15 km (~ 6.2–9.3 miles) in continental crust, below which rock becomes less likely to fracture and more likely to deform ductilely. The zone exists because as depth increases confining pressure increases, and brittle strength increases …
