This work aims to review and discuss with new interpretations the tectonic evolution of the Ivrea Verbano Zone (IVZ), to highlight how inheritance from previous orogenic cycles may have driven the Mesozoic Alpine Tethys rifting processes. After the Mesozoic rifting, the IVZ was located at the base of the continental crust of the Adriatic distal margin, before being exhumed at the surface during Alpine orogenesis. Different compositions of the IVZ peridotite massifs, mostly lherzolitic and harzburgitic, reflect upper mantle processes developed since late Proterozoic-early Paleozoic, when a sub-Gondwanian lherzolitic mantle slice (Balmuccia-type) coexisted with a depleted harzburgitic raft (Finero-type). After the buildup of the Variscan chain, in the Carboniferous, the overthickened crust might start to delaminate at its base. Whereas the Balmuccia body behaved as a passive witness of the Paleozoic mantle differentiation, the Finero mantle section underwent pervasive K-metasomatism in late Carboniferous to early Permian, triggered by melting of delaminated lower crustal slabs. Asthenosphere mantle decompression in the early Permian generated basic magmas emplaced in the lower crust. They led to a significant lateral variation of the crustal rheology, which probably drove the subsequent Triassic to Jurassic extensional tectonic pulses to delocalize along weaker zones. The Finero peridotite was characterized by a relatively low density, which was enhanced by the K-metasomatism, thereby promoting its exhumation near one of these weak zones, during a late Triassic-early Jurassic extensional pulse. Thus, the Alpine rift and, in general, magma-poor rift localization can be considered as the final product of deep processes predating the onset of rifting extensional tectonics s.s., which may have promoted crustal excision and mantle exhumation at specific locations.

这项工作旨在通过新的解释来回顾和讨论伊夫雷亚韦尔巴诺带 (IVZ) 的构造演化，以强调先前造山周期的继承可能如何驱动中生代高山特提斯裂谷过程。中生代裂谷之后，IVZ 位于亚得里亚海远缘大陆地壳的底部，然后在阿尔卑斯山造山运动期间被挖掘到地表。IVZ 橄榄岩地块的不同成分，主要是二辉橄榄岩和辉长辉岩，反映了晚元古代-早古生代以来发展的上地幔过程，当时亚冈瓦纪二辉辉岩地幔片（Balmuccia 型）与贫化的辉长辉岩筏（Finero 型）共存。在瓦力斯坎链形成之后，在石炭纪，过度增厚的地壳可能会在其底部开始分层。Balmuccia 体是古生代地幔分异的被动见证，而 Finero 地幔部分在石炭纪晚期至二叠纪早期经历了普遍的 K 代代作用，这是由分层的下地壳板片的熔融引发的。早二叠世软流圈地幔减压产生了侵位下地壳的基性岩浆。它们导致了地壳流变学的显着横向变化，这可能驱使随后的三叠纪至侏罗纪伸展构造脉冲沿着较弱的区域离域。Finero 橄榄岩的特点是密度相对较低，在晚三叠世至早侏罗世的伸展脉冲期间，K 交代作用增强了密度，从而促进了其在这些薄弱带之一附近的折返。因此，阿尔卑斯裂谷，一般来说，
