“…Subalkali granite and leucogranite of the Gurakhta and Panimba plutons localized in the same fault zones in the central Transangarian are similar in age (~700 Ma) and geochemistry. The same age was established for carbonatites and linear type alkaline metasomatic rocks with economic apatite-pyrochlore mineralization, which occur as extended (up to 2.5 km) lit par lit and lenticular bodies controlled by dislocations of the Tatarka deep fault [5].…”

“…The Middle Vorogovka massif and a num ber of alkali granite and syenite intrusions in the framework of the Uvolga Graben and the Upper Vorogovka Graben Syncline are related to this com plex [38,40]. Subalkali granite and leucogranite of the Tatarka pluton correspond to the same time level (630 Ma) [5]. The Late Neoproterozoic alkaline mag matism and formation of marginal continental troughs under extension conditions are traced along the entire Yenisei Ridge and the Eastern Sayan Range up to the Lake Baikal [37,60].…”

“…These results are consis tent with the age of metamorphic rocks in the north western Sayan region [37] incorporated together with the Yenisei Ridge into the Sayan-Yenisei accretionary belt. The age of metamorphism of the accreted island arcs in the Isakov Block (~630 Ma) [5] situated to the west (in present day coordinates) of the Cis Yenisei Block in the Yenisei Ridge and the Late Neoprotero zoic age of the overlying molasse complexes do not contradict this interpretation [37].…”

“…Subvolcanic bodies of alka line gabbroids and nepheline syenites are localized among comagmatic volcanic rocks of the trachyba salt-trachyte association (700 Ma) of the Chingasan Group [38]. To the south, in the Transangarian, the coeval Middle Tatarka nepheline syenite massif is located in the same zone [5]. Subalkaline A granites of the Kutukas (Gurakhta) Complex exposed at the Chapa-Vorogovka interfluve are related to the same epoch.…”

Grenville tectonic events and evolution of the Yenisei Ridge at the western margin of the Siberian Craton

et al. 2014

Geological, petrologic, geochemical, and isotopic geochronological evidence for Grenville events at the western margin of the Siberian Craton are considered. These events were related to assembly of the Rodinia supercontinent. Multiple manifestations of riftogenic and within plate magmatism at the final stage of orogenic evolution gave rise to breakdown of Rodinia and the formation of the Paleoasian ocean. The results allowed us to develop a new concept on the Precambrian geological evolution of the Yenisei Ridge and the processes that created its tectonic structure. The chronological sequence of events in the history of the Transangarian Yenisei Ridge is based on geological evidence and isotopic dating of Precambrian complexes variable in geodynamic nature. Four tectonic stages dated at 1.4-1.1, 1.1-0.9, 0.90-0.85, and 0.8-0.6 Ga were controlled by collision and extension recognized from large regional linear crustal structural elements. The evolution of the Transangarian Yenisei Ridge, which lasted for ~650 Ma, corresponds in duration to supercontinental cycles that begin from rifting and breakdown of the predated supercontinent and was com pleted by orogeny and the formation of a new supercontinent. The regional geodynamic history correlates with the synchronous sequence and similar style of tectonothermal events at the periphery of the large Pre cambrian Laurentia and Baltica cratons. This is evidenced by paleocontinental reconstructions, which con firm close spatiotemporal links of Siberia with cratons in the northern Atlantic 1400-600 Ma ago and indi cate incorporation of the Siberian Craton into the ancient Nuna and Rodinia supercontinents.

“…The origin of Neoproterozoic dikes and associating igneous rocks in the fold belts of the margins of the Siberian Craton is a debatable topic. These magmatic complexes were considered in connection to various geodynamic settings, such as continental rifting during the breakup of the Rodinia supercontinent [15,16], or an active continental margin of Siberia [10,14,[17][18][19][20][21] on the early formation stages of the Central Asian fold belt. To solve these discussions, we will give particular attention to the nature, composition, and age of the Neoproterozoic mafic, intermediate, and felsic dikes.…”

Early Ediacaran Magmatism in the Yenisei Ridge and Evolution of the Southwestern Margin of the Siberian Craton

et al. 2020

We present the first comprehensive data for the early Ediacaran stage of evolution of the western active continental margin of the Siberian Craton (Yenisei Ridge). U-Pb (SHRIMP-II SIMS) data for zircons from dikes of picrodolerites, quartz diorites, and leucocratic granites show that they were emplaced at 625 ± 5, 623 ± 8, and 626 ± 5 Ma, respectively, which indicates a narrow time window of Ediacaran magmatic events. The mafic tholeiitic rocks have OIB and E-MORB mantle components in their magmatic sources. Mineralogical and geochemical observations showed that the mantle-sourced mafic melts assimilated some crustal material, forming Th-enriched dikes of intermediate composition and K- and Rb-enriched felsic rocks. The possible geodynamic conditions for the formation of these early Ediacaran dikes are shown and a geodynamic model is presented for the development of the Yenisei Ridge orogen from the late Cryogenian to the late Ediacaran.
