“…New geological and structural, mineralogical and pet rological, and isotopic geochronological data consid ered in terms of recent knowledge on supercontinental cycles [53] allowed us to specify the evolution of the Earth's crust in the region. Especially noteworthy are the first precision data on the Mesoproterozoic and Early Neoproterozoic Transangarian history, which testified to the breakdown of the Nuna supercontinent followed by the Grenville events that resulted in assembly of the Rodinia supercontinent.…”

“…Close association of diverse igneous and metamorphic complexes testi fies to the complex regional structure. The reconstruc tion of its geological history is important not only for understanding the tectonic evolution of mobile belts in the framework of ancient cratons, but also for support ing incorporation of the Siberian Craton into the ancient Nuna (Columbia) and Rodinia superconti nents [53,71]. It is assumed that this period of terres trial tectonic evolution covered the time interval from 1.7 to 0.7 Ga, which was characterized by relatively low endogenic activity due to rearrangement of con vective mantle flows and plumes [70].…”

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.

“…If we take into account the boundaries of the most intense rearrangements in the history of the Earth, then it corresponds to geological periods and, on average, is about 55 million years [22]. The possibility of manifestation of planetary geotectonic phases is discussed [43,52,53,69,73,81,103,133,134,[139][140][141]. At the same time, based on the frequency of similar geological formations and their complexes, their age and duration of formation, taking into account the main geotectonic boundaries, many researchers recognize the periodicity and cyclicity of the development and formation of the Earthʹs crust.…”

Аннотация . Периодически развиваются самоподобные движения структурно-вещественных комплексов (СМК) из состава Солнечной системы в течение периода около 4,5 миллиардов лет земной коры, развития Земли в условиях самоорганизации. Синхронные или близкие во времени ряды генетических или парагенетических групп магматических, рудно-минеральных, метасоматических, осадочных образований, их структур и других сопутствующих им процессов, включают в себя каждый комплекс (ГМК). Каждый комплекс в его пределах ограничен во времени и пространстве, по причине признаков самопроизвольного динамического процесса; распространяется на территорию Земли в текущий исторический период; формирует состав и структуру земной коры на этом этапе, определяя ее полициклическое развитие.

“…From 5-7 to 17 and 22 subdivisions are distinguished depending on the principle of determining the boundary geodynamic, and structural boundaries [52-54, 73, 74, 25 ]. The speed of geological processes is different [75], and the nature of the movement is oscillatory [167,93,90,141,100]. Different meanings and mechanisms of origin, however, many authors invest in this understanding.…”

Annotation. The self-similar dynamic structural-material complexes (SMC) from the composition of the Solar System over a period of about 4.5 billion years of the earth's crust, of the Earth's development under the conditions of self-organization, are periodically formed. The synchronous or close-in-time series of genetically or paragenetically related igneous, ore-mineral, metasomatic, sedimentary formations, their structures, and other processes accompanying them, each complex (SMC) includes. Each complex in its formation is limited in time and space, according to the manifestation of the features of a spontaneous dynamic process; spreads in the volume of the Earth in a certain historical period; forms the composition and structure of the Earth's crust at this stage, its polycyclic development determining. The number of cycles is about 14, with decreasing duration of their manifestation.
