Tectonic foliation occurs under which of the following conditions?
A)ductile,shear stress
B)ductile,tensional stress
C)brittle,shear stress
D)brittle,compressional stress

Question

Quizplus · Accepted Answer

Tectonic foliation is a type of foliation that develops due to ductile deformation caused by shear stress. The force of this stress can cause the minerals in the rock to align in a particular direction, resulting in a foliation pattern. Tensional stress can cause stretching and cracking in the rock, but not necessarily align minerals in a specific direction. Brittle deformation under compressional stress can result in faults or joints, but not tectonic foliation.
