WebFeb 6, 2024 · Use Byerlee's law to determine if the fault should fail. Figure 1.4. 2: Tectonic stress and lithostatic stress acting on a rock result in normal stress and shear stress acting on a fault surface. Because σ n > 200 MPa, we use the second part of Byerlee's law: τ = 50 + 0.6 ( 300) = 50 + 180 = 230 MPa. WebIdentifying the type of fault allows us to determine if the body of rock was under compression or extension at the time of faulting. Complete the table below the images, …
