the lorestan (or lurestan) domain forms the northerly of the two main salients in the zagros ftb. the structural style of the simply folded zone is interpreted here to be dominated by detachment folding with some degree of disharmonic folding (folding of differing wavelengths at different structural levels). the disharmony occurs between a deeper layer bounded by the basal and dashtak formation décollement levels and shallower one between the dashtak décollement and the surface. there is also evidence of a thick-skinned element to the deformation. the lack of hormuz salt exposed at the surface makes the nature of the basal detachment less certain than in the fars domain, but the presence of this salt layer is inferred from the observation that the taper angle (the angle between the basal detachment and the current topographic slope) is identical to that where the salt is proven further south.
