Supplementary Fig. S5. PSYJB21 and TNT00 estimates for clinopyroxene xenocrysts from dyke 6 lamproite and modelled mantle paleogeotherm calculated using the FITPLOT program. Dashed lines margin the FITPLOT error. Diamond (D)–graphite (G) transition from Day et al. (2012). For comparison modelled mantle paleogeotherms beneath Udachnaya pipe, Siberian craton (Dymshits et al. 2020) and Bultfontain pipe, Kaapvaal craton (Mather et al. 2011) are shown. Present-day lithosphere-asthenosphere boundary (LAB) from Cherepanova et al. (2015) and data of East Siberian Research Institute of Geology, Geophysics and Mineral Raw Materials (Irkutsk).
