Tectonic evolution of the Zanhuang fold nappe—thrust belt from a subduction initiation at circa 2700 Ma, b arc magmatism during 2692–2550 Ma, to c emplacement of the boninite and Buddha nappes over the passive margin on the Eastern Block at 2520 Ma, and metamorphism and foreland basin sedimentation continuing until 2450 Ma. a Adapted from Whattam and Stern7 with permission from [Springer Customer Service Centre GmbH] [Springer] [Contributions to Mineralogy & Petrology] [The ‘subduction initiation rule’: A key for linking ophiolites, intra-oceanic forearcs, and subduction initiation.
