Three geometric models concerning the development mechanisms of fold-accommodation faults, namely concentric folding, kink-band folding, buckle flexural-slip folding, are summarized. Five well-exposed meter-scale folds with minor faults are analyzed in detail. They developed within Meso-and Neoproterozoic sequence in central intraplate Yanshan Orogenic Belt, northern North China Craton. Some preexisting faults may serve as nucleation sites during followed folding deformation and finally lead to the formation of hinge wedges. Development of fold-accommodation faults may be effectively influenced by buckling flexural-slip folding, tightness change of folds and escape of incompetent units from cores of folds.
