Discussion: En echelon fold patterns can be explained by strike-slip displacement approximately parallel to the arrays (trend of regional fold axes) or by reactivation of pre-existing faults in a rotated stress field. Although en echelon fold patterns commonly develop in strike-slip terranes, they are typically

The fold is intruded by an undeformed Sinemurian diabase dike of Rossville composition, parallel to the extension veins. The data show a consistent strain pattern, from the Upper Triassic through the Lower Jurassic, of northeast shortening and northwest extension, and suggest that en echelon folds formed along an east-trending sinistral shear couple.

Cobbold, P. R. Wrench zones commonly show en-echelon patterns of folds in the stratified cover above a basement fault (examples are the Darien Basin in Panama and the Inglewood fault trend in California). Folds are often associated with synthetic and antithetic wrench faults, but the time relationships between folds and faults may not be obvious.

low heat flow. Model of decoupling and very low strength faults (e.g. Mount & Suppe, 1987). Map of southern part of San Andreas plate boundary, showing the main strike-slip faults (including the San Andreas) and associated structures. Fold causes that do not contribute to significant fold growth in all three dimensions, such as en-echelon folds, drag folds and rollover anticline are not in these groups.
