“…Lamprophyres are produced by preferential partial melting of metasomatized portions of the SCLM (e.g., Dongre and Tappe, 2019;Maria and Luhr, 2008;Rock et al, 1991;Wang et al, 2022). They are often rich in hydrous minerals (e.g., amphibole and biotite), volatiles (e.g., S, Cl, and H 2 O), alkalis, fluid-mobile incompatible elements (e.g., K, Ba, and Rb) (e.g., Rock, 1987;Rock and Groves, 1988;Wang et al, 2022). Since lamprophyres are derived from relatively large regions of mantle then, in the absence of significant crustal contamination and other secondary processes, they are more homogeneous and representative than mantle xenoliths (Wang et al, 2022;Wang et al, 2020), and could better reflect the nature of the SCLM from a broader domain, as well as the mobilization of halogens during the ascent of lamprophyre melts.…”
