**6. Examples of Orogenic belts resulting from Ampherer-subduction zones**

Ideal examples of orogens resulting from the closure of a hyperextended rift system or an immature ocean include the Alps [34], Pyrenees [136, 137], and European Variscides [138, 139]. These orogens often occurred without significant subductionrelated magmatic activity, so the original rock units before the collision were relatively well preserved [34, 43, 44, 137, 140].
