WebElastic rebound: We've briefly discussed brittle and ductile deformation. What do these terms really mean? Elastic deformation: Generally, when a solid is strained, it will return to its original shape when the stress is … The 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 with confining pressure whil… WebThe mineral assemblage comprising quartz, feldspar, biotite and hornblende suggests lower greenschist facies conditions during mylonitisation, with the contrasting ductile behaviour of quartz and brittle fracturing of feldspars … frog hybrid cycle
