Light oxygen isotopes in mantle-derived magmas reflect assimilation of sub-continental lithospheric mantle material
Oxygen isotope ratios in mantle-derived magmas that differ from typical mantle values are
generally attributed to crustal contamination, deeply subducted crustal material in the mantle …
