Carbon and oxygen isotope composition of rocks of alkaline complexes and the host metacarbonate deposits. a, δ13С–δ18О diagram: PIC, domain of primary magmatogene carbonatites (Conway and Taylor, 1969); NSC, marine sedimentary carbonates (Pokrovskii, 2000). Arrows show the influence of crustal contamination and low-temperature hydrotherms (Demény et al., 1998). МСС, assumed field of mantle–crustal carbonatites (Vrublevskii, 2017). Gray fields mark predominant calcite/dolomite compositions in carbonatites of Kuznetsk Alatau, Central Tuva (CT), and Turkestan–Alai segment of the Tien Shan (TSh) (Nikiforov et al., 2006; Vrublevskii, 2015; Vrublevskii et al., 2018c).
