FIG. F-4. Fault types. (a) A secondary antithetic fault, has throw in the direction opposite to that of the primary fault P and secondary synthetic fault S. (b) Faulting involving rotation that increases the throw of the fault. (c) Growth fault curved (listric) in both plan and cross-section. Fault movement contemporaneous with deposition produces thickening into the fault and a rollover anticline. (d) Development of a duplex structure by thrust faulting (overthrusting or underthrusting)[1].
FIG. F-4. Fault types. (Continued). (e) Wrench (strike-slip) faulting. A wrench fault often has associated secondary wrench, normal, and thrust faults and folding at roughly 30° to the wrench fault. Wrench fault traces are often en echelon rather than continuous. (f) Right-lateral wrench fault. Components of convergence or divergence may produce flower structures (see Figure F-12). (From Sheriff and Geldart, 1995, 369–370.) (g) Transitions from fault to fault may be accompanied by tear faults, folds, or in other ways. (h) Faulting associated with subduction zone. The accretionary wedge is generally built by underthrusting. (From Lowell, 1985.) (i) Transform fault offsetting spreading center. Rift faulting associated with extension is usually asymmetric[2].
