New GEOLOGY paper about the lateral fold growth and fold linkage

A three-dimensional finite element model is used to mechanically investigate for the first time the lateral linkage mode of two initially isolated fold segments.

The transition from linkage to no linkage occurs when the fold separation between the initially isolated folds is slightly larger than one-half of the fold wavelength. A natural example of lateral fold linkage from the Kirkuk oil field (Kurdistan region of Iraq) demonstrates the economic interest of saddle points linking the initially isolated fold segments.
