“…These metasomes may have formed during the Caledonian collision [88] because of the input of volatile-rich crustal material into mantle peridotites, which react with peridotites and form phlogopite-rich assemblages. The influence of phlogopite metasomes was significantly less for the post-trap UMLs of the Chadobets complex, while the contribution of carbonate metasomatism increased [32].…”

“…Within the Irkineeva-Chadobets Trough, in addition to the Chadobets complex (which includes the Terina complex) formed in the post-trap period, there is another UML complex: Ilbokich (Figure 1), which is a product of pre-trap magmatism. Detailed studies of the isotopic characteristics of these complexes showed that the melts had a predominant moderately depleted mantle source with the addition of the material from the SCLM [31,32]. It was concluded that the SCLM source involved in the magma generation of the complexes changed over time.…”

“…Emplacement of the Chadobets alkaline rocks includes several stages of the intrusion of aillikites, mela-aillikites, carbonatites, and damtjernites. The crystallization of the rocks has been related to the Permian-Triassic Siberian plume activity forming the Siberian large igneous province (LIP), and the Chadobets UML-carbonatite complex was intruded in the southern part of the Siberian plume activity (Figure 1a) [30][31][32][33][34]. The dates for the Chadobets rocks are 256.7 ± 1.1 Ma and 252 ± 12 Ma (zircon from damtjernite, and perovskite from aillikite, respectively, U-Pb, Chuktukon complex) [31,33], 243.4 ± 3.1 and 241 ± 1 Ma (Ar-Ar, phlogopite, and Rb-Sr, respectively, aillikites from Terina complex) [32], and 231 ± 2.7 Ma (rippite, Ar-Ar, Chuktukon carbonatites) [31].…”

“…The Devonian Ilbokich UML complex is located approximately 70 km to the southwest of the Chadobets upland (Figure 1c). The age of crystallization of the Ilbokich UMLs is 399 ± 4 Ma (perovskite, U-Pb) [32]. The aillikite and damtjernite dykes, which form the Ilbokich UML complex, are up to 5-10 m thick [23].…”

“…As group I kimberlites, they are igneous rocks with a deep mantle source, which do not bear significant signs of assimilation of crustal material captured during the rise of the melt [1][2][3]. Like kimberlites, they are significantly depleted in SiO 2 (18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35) wt% SiO 2 ) and are characterized by a high total content of magmatic carbonates [4][5][6]. A distinctive feature of aillikites is their higher Fe content (compared to kimberlites) [7].…”

Polygenic Nature of Olivines from the Ultramafic Lamprophyres of the Terina Complex (Chadobets Upland, Siberian Platform) Based on Trace Element Composition, Crystalline, and Melt Inclusion Data

Olivine from the deep mantle-derived rocks, such as ultramafic lamprophyres, carries important information about the composition of the mantle source, the processes of mantle metasomatism, the origin of specific silicate-carbonate melts, as well as the composition and mechanisms of crystallization of these rocks. Textures and compositions of olivine from the carbonate-rich ultramafic lamprophyres (aillikites) of the Terina complex, along with their mineral and melt inclusions, exposed that olivines have different sources. Two populations of olivines were considered: macrocrysts (>1 mm) and groundmass olivines (<1 mm). Groundmass olivines are phenocrysts and characterized by weak variations in Mg# (84–86.5), a sharp increase in Ca and Ti contents, and a decrease in Ni and Cr from core to rim. They have higher concentrations of Li, Cu, Ti, and Na compared to macrocrysts. Among the macrocrysts, the following populations are observed: (1) high-Mg olivines (Mg# 89–91) with high Ni and low Ti contents, which are interpreted as xenocrysts from the slightly depleted lherzolite mantle; (2) high-Ca olivines (Mg# 84–88, CaO 0.13–0.21 wt %), which have patterns similar to groundmass olivines and are interpreted as cumulates of early portions of aillikite melt; (3) macrocrysts with wide variations in Mg# (73–88), low CaO contents (0.04–0.11 wt %), and positive slope in Ca vs. Al and negative slope in Ca vs. Mn, which are interpreted as disintegrated megacrysts from the Cr-poor megacryst suite. The megacryst suite could have been formed in the pre-trap period during the melting of the metasomatized subcontinental lithospheric mantle (SCLM). The aillikite melt evolution is traced by secondary melt inclusions in olivine macrocrysts: early phlogopite-diopside-calcite-apatite association, containing Ti-magnetite and ilmenite, is followed by an association with magnetite and sulfides (pyrrhotite and pentlandite); finally, at a late stage, inclusions with a predominance of Ca-Na-carbonates and sulfates and enriched in U, Th, Y, REEs, Sr, and Ba were captured.

The article reports morphotectonic and petrological characteristics of magmatic systems of Permo-Triassic traps in the sedimentary cover of the Siberian Craton, Taimyr, as well as in the crystalline basement of the Mesozoic cover of the West Siberian Plate and the Kara sedimentary basin based on the relief analysis, seismotomography data, magnetic and gravitational anomalies. Four development sectors of magma-permeable zones were distinguished along the perimeter of the craton of the Anabar Shield. The western sector is characterized by an extensive stretching area, on which the lava region of volcanic ridges junction of the Tunguska syncline formed. A striking feature of subaerial volcanism is the meridional petrochemical trend of increasing the silica of basic magmas in intrusive rocks of the Siberian Craton while the volumes of embedded melts are reduced.
