-->  (FACING PAGE) Figure 16. Examples of subsidiary folds developed in the synclinal core. Note how the lower layers in both examples are broadly folded into their synclinal form, whereas upper layers exhibit a number of smaller-scale folds. Typical of parallel-folded synclines, these tighten upsection and the smaller-scale folds record the compression resulting from this upward tightening. Example (B) is from Willis et al. (2001, reproduced with permission of the Gulf Coast Association of Geological Societies).
