From: Carbonate- and silicate-metasomatized mantle beneath Himalayan-Tibetan orogenic belt

A Ol-Opx-Cpx triangular plot for peridotites and pyroxenite xenoliths. B MgO (wt%) vs. Al2O3 (wt%) diagram. Values of primitive upper mantle (PUM) are collected from ref. 30. C Chondrite-normalized REE patterns. D Primitive mantle-normalized multielement patterns. The values for chondrite and primitive mantle were taken from ref. 42. E 143Nd/144Nd vs. 87Sr/86Sr ratios diagram. F (La/Yb)N vs. 87Sr/86Sr ratios diagram. In xenoliths of OPG and ORG, (La/Yb)N ratios show strong positive correlation with 87Sr/86Sr ratios, R2 = 0.69 and 0.90, respectively. G Nb/Ta vs. (La/Yb)N ratios. H SiO2 (wt%) vs. (La/Yb)N ratios. The data source is Supplementary Data 1.
