Here we present new data from the southernmost part of the Supporting Information: • Supporting Information S1 oroclinal structure, the Manning Orocline, which supposedly developed in the Early Permian, contemporaneously and/or shortly after the deposition of the Lower Permian Manning Basin. New U-Pb detrital zircon data provide Correspondence to: a maximum depositional age of ~288 Ma. Structural evidence from rocks of the Manning Basin indicates that L. White, both bedding and preoroclinal fold axial planes are approximately oriented parallel to the trace of the Manning

Brittle deformation was dominated by sinistral strike-slip faulting, particularly along a major fault zone (Peel-Manning Fault System), which is marked by the occurrence of a serpentinitic mélange, and separates Citation: tectonostratigraphic units of the New England Orogen. Our revised geological map shows that the Manning White, L., G. Rosenbaum, C. M. Allen, and U. Shaanan (2016), Orocline-driven Basin is bounded by faults and serpentinites, thus indicating that basin formation was intimately linked to transtensional basins: Insights from the deformation along the Peel-Manning Fault System.
