Zircon data from South Karakoram gneiss dome provide evidence for Proterozoic inherited cores (1.8-1.9 Ga and 2.3-.2.5 Ga) surrounded by migmatitic overgrowth with ages ranging from ∼6 to ∼20Ma. Oxygen isotopic data of Neogene migmatite and inherited core is similar and indistin…

High-silica rhyolites (>75 wt% SiO2) are the most differentiated magmas on Earth. Though rare in subduction volcanism, they erupt in large volumes (100–1000s km3) in extensional settings. Understanding their generation is crucial as rhyolite formation substantially alters the…
