摘要: The coalescence and spatial variability of different thrust-related folding mechanisms involving the same mechanical multilayer along a curved thrust system are documented in this study. field-based analysis folds spectacularly exposed Gran Sasso system, Central Apennines Italy, allowed us to reconstruct interference fold pattern between fault-bend fault-propagation folding. These two exhibit differently oriented ramps passing from one style other. Their selective development is controlled by contrasting styles compressional normal-fault reactivation related positive tectonic inversion. Fault-bend interact with characteristic salient apex zone due their synchronous/in-sequence growth. This might be helpful predictive when reconstructing lateral variations similar subaerial or submarine belts.
