“…The SCLM beneath the Archaean cratons is characterized by (a) comparatively low geothermal gradient, (b) higher thickness and density, and (c) lack of extensive convection-related mixing and it acts as a lid to the hot convecting asthenospheric mantle beneath. Geophysical studies over the years have shown that the SCLM is considered to be formed by accretion of arc and oceanic lithospheres (Lee, 2006;Pollack, 1986;Su & Chen, 2018). Besides, SCLM is the most heterogeneous and chemically distinct geochemical reservoir capable of generating melts with exotic compositions, such as, lamproites and orangeites (Chalapathi Rao, Creaser, Lehmann, & Panwar, 2013;Krmícek, Romer, Ulrych, Glodny, & Prevelic, 2016;Pearson & Nowell, 2002).…”
