WebOn strike-slip faults the motion is typically only horizontal, or with a very small vertical component, and as discussed above the sense of motion can be right lateral (the far side moves to the right), as in Figures 12.12 and 12.13, or it can be left lateral (the far side moves to the left). Transform faults are strike-slip faults. WebWhen tensional stresses pull crust apart, it breaks into blocks that slide up and drop down along normal faults. The result is alternating mountains and valleys, known as a basin-and-range (figure 19). Figure 19. dr thomas kay valparaisoWebAnderson'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. dr thomas kearney death
