(A) Minimum modeled spike duration constrained by the Belfond Dome eruption. Errors on modeled spike duration are 2σ. (B) Summary of mush rejuvenation events recorded by zircon U-Th model ages and Ti-in zircon temperatures within selected cogenetic enclaves and Belfond Dome lava. Errors are 1σ. Mush rejuvenation duration from our model. T_solidus estimated by the lowest Ti-in zircon temperature from the zircon in the lava. T_{liquidus andesite} from ref. 35. Minimum spike temperature estimated by the highest Ti-in zircon temperature from the cogenetic enclaves.
