Fig. 10. Formation and evolution of strike-slip faults at different periods (Pre-Sinian rift is modified from References [27-28], basement faults are revised from Reference [29]). σ3—minimum principal stress; σ3a—the component of minimum principal stress perpendicular to pre-existing structural weakness zone; σ3b—the component of minimum principal stress along pre-existing structural weakness zone; α—the angle between the minimum principal stress and pre-existing structural weakness zone. |
