"Travyanaya has higher PGE concentrations and features an enrichment in PPGE relative to IPGE with positive Pd as well as Rh anomalies and a high Pd/Ir ratio of more than 75 (Figs. 12 J, 14 A). Chromite-rich dunite from the Dunite Block exhibits a strong enrichment in IPGE relative to PPGE, which reflects the presence of IPGE-rich cumulus chromite (e.g., Capobianco and Drake, 1990). All other lithologies from Travyanaya, ranging from websterite to orthopyroxenite and gabbronorite, have remarkably similar patterns with Pd/Ir ratios from 48 to 65 and positive Pd as well as Rh anomalies (Fig. 14 B). Kumuzhya, Nittis and Nyud lithologies also show positive Pd and Rh anomalies and relatively high Pd/Ir ratios of more than 20 (Fig. 14 C, D, E). Only the ophitic orthopyroxenite from Nittis has a different pattern lacking distinct anomalies. It is worth noting that the positive Pd and Rh anomalies are characteristic of many other Fennoscandian intrusions of similar age, such as the Portimo Complex, and also in parts of the Great Dyke of Zimbabwe and the Muskox intrusion in Canada (Barnes and Francis, 1995; Iljina et al., 1992; Maier et al., 2015)."
