WebJun 1, 1976 · If precise measurements of fold form are used to establish small interlimb angles, it is unsatisfactory to have no accurately defined limits for isoclinal folds. It is suggested that interlimb angles of +3° and −3° be used to separate isoclinal folds from tight and elasticas folds, respectively. WebTo decide which interlimb angle to use requires that you have some additional knowledge about the shape of the fold. If the fold is tightly closed and has an interlimb angle of less than 90°, then you would use … WebNov 1, 2024 · Fold orientation can be used to discriminate between pure contraction (b), pure strike-slip (c), transpression (d), and transtension zones (e). f) Asymmetrical folds in a shear zone, indicating sense of shear. g) Example of extensional fold developed in the hangingwall to a 10 km displacement fault in the North Sea rift basin. scrapbooking custom

WebThe minimum interlimb angle was observed at the initial irregularity fold. Fold propagation in which lateral spreading of a fold takes place as a periodic structure is called as transverse fold propagation. The concept of fold propagation is important because it explains as to why fold interlimb angles vary in a single fold complex (Fig. 3.24e).
