Ramsay's classification of folds
Webb26 okt. 2024 · Fold Division on the basis of "Dip Isogon" { John Ramsay's Classification } Class 1: Dip isogons converge toward the inner arc, which is tighter than the outer arc. Class 2 (similar folds, also called shear folds): Dip isogons parallel the axial trace. The shapes of the inner and outer arcs are identical. WebbA). These folds are developed as a result of strong later compression of earlier folds having initial non-rectilinear axes (Mukhopadhyay and Sengupta, 1979). The eyed folds are the planar view of the three dimensionally developed dome and basin (Type-1 of Ramsay, 1967) interference structures with variable styles. 4.2. Mirror Image Folds
