Description

Based on mineralogical composition and the presence of typomorphic minerals, Chadobec UMLs are classified as aillikite, cpx-aillikite, mela-aillikite and damtjernite. Ilbokich UMLs are represented by aillikite and damtjernite, grading into carbonatite. All UMLs are texturally heterogeneous and have a variety mineral composition and wide variation in the content of minerals, especially of carbonate, clinopyroxene aillikite and alkali feldspar and alkaline minerals in damtjernite (Nosova et al., 2018). In Table S1 the mineral composition and brief petrography description of isotopic studied samples is presented according to (Nosova et al., 2018).
