WebAnderson's theory classifies tectonic environments into three fault regimes based on their relationship with the principal stresses. σ ₁ being the vertical stress is classified as a gravity regime because movement aligns with the force of gravity. This regime dominated by normal dip-slip faults. A vertical σ ₃ is classified as a thrust regime. WebMay 12, 2024 · NORMAL: Normal faults occur at divergent plate boundaries.

WebCauses of Geological Faults Geological faults happen when stress occurs and determines the fault’s type after the event. There are three main categories of stress: Compression stress Occurs at convergent plate boundaries. The plates move and crash toward each other.
