 The Cusps splay in the East Iran origin is characterized by multiple buckling phases, resulting in the formation of a multi-plunging anticline and syncline. These structures were formed through flexural slip, which was identified as a significant mechanism for their development. Parasitic folds, active folds, and strike-slip duplexes suggest that flexural slip occurred on discrete movement horizons among the rock units. Additionally, shortening estimates from profiles in the Shek Arab-Inclined Transpressional Zone range from 33% to 68%, indicating that the Cusps splay underwent complex deformation processes.
