When do rocks succumb to ductile deformation?
A) on the rims of meteorite impact craters
B) in fault zones with intermittent high strain rates
C) at great depth under active mountain belts with high confining pressure and low strain rates or prolonged strain
D) at shallow depth, at low confining pressure, and low temperature

Question

Quizplus · Accepted Answer

Rocks succumb to ductile deformation at great depth under active mountain belts where there is high confining pressure and either low strain rates or prolonged strain. This allows the rocks to deform plastically rather than fracturing.
