Question

Which of the following scenarios best describes the deformation that will occur in different parts of the crust?

Brittle deformation is dominant in the shallow crust; ductile deformation is dominant in the deep crust.
Ductile deformation is dominant in the shallow crust; brittle deformation is dominant in the deep crust.
Folding and fracturing only occur in the shallow crust, where there is less confining force.
Folding and fracturing only occur in the deep crust, where there is more tectonic force.

Answer 1

A. Brittle deformation is dominant in the shallow crust; ductile deformation is dominant in the deep crust.
