Derivation of Jurassic HIMU-like intraplate basalts from mantle transition zone in South China: New geochemical constraints from olivine-hosted melt inclusion

The petrogenesis of high-μ (HIMU, μ = 238U/204Pb) basalt in a continental setting remains highly controversial. Here we present a comprehensive geochemical (including major and trace element and isotopic compositions of whole-rock, olivine and melt inclusion) data on Jurassic HIMU-like basalts from the interior (Antang) of South China. This study identified high-H2O (up to 5.0 wt%) olivine-hosted melt inclusions in these basalts. After stripping...
