[Retracted] Initiation of Triangle Zones by Delamination, Shear, and Compaction at the Front of Fold-and-Thrust Belts

Figure 1

This prototype summarizes the three features of the triangle zones which are studied: the change in depth of the décollement, the delamination of the upper décollement, and the curving of the fault (back thrust). These deformation mechanisms require a combination of slip, opening, and compaction on the various velocity discontinuities.
