In-situ lithium (Li) concentrations and δ 7 Li of olivine, orthopyroxene (opx) and clinopyroxene (cpx) in mantle xenoliths from the Quaternary Longgang maar provide insights into the nature and evolution of the lithospheric mantle beneath the easterly part of the North China Craton. SIMS analyses show Li partitioning of olivine>opx≥cpx and Li isotopic disequilibrium in each sample. Olivines...
