Isotopic variation in Semail Ophiolite lower crust reveals crustal-level melt aggregation Vrije Universiteit Brussel
The scale and magnitude of compositional heterogeneity in the mantle has important implications for the understanding of the evolution of Earth. Hetero- geneity of the upper mantle is often evaluated based on mid-ocean ridge basalt compositions, despite their homogenisation prior to eruption. In this study we present Nd and Sr isotope data obtained by micro-drilling single plagioclase and clinopyroxene crystals in gabbroic cumulates of the ...
