What is the condition of formation of strike-slip fault?
Understand the Problem
The question is asking for the conditions that lead to the formation of a strike-slip fault, which involves understanding geological stress orientations.
Answer
σ2 vertical, σ1 horizontal
The final answer is σ2 vertical, σ1 horizontal.
Answer for screen readers
The final answer is σ2 vertical, σ1 horizontal.
More Information
Strike-slip faults are characterized by the horizontal movement of blocks of rock separated by a fault plane, driven primarily by horizontal shearing stresses.
Tips
Commonly, students might confuse the orientation of the stresses. Remember that the maximum principal stress (σ1) is horizontal, facilitating horizontal displacement.
