Abstract
The lithogeochemical peculiarities (content and distribution of main rock-forming oxides, as well as some trace elements) of clayey rocks of the Volynian, Redkinian, Kotlinian, and Lower Cambrian stratigraphic levels of the west of the East European Plate (Belarus and Volyn, east of the Baltic Monocline, and Moscow Syneclise) are analyzed. Using various lithogeochemical approaches and methods and data on U–Pb isotopic age of detrital zircon populations, which occur in sandstones associated with mudstones, and taking into account geochemical peculiarities of possible source rocks of fine-grained alumosiliciclastic material (igneous associations of different composition and age of Sarmatia and Fennoscandia), we provided ideas on a possible contribution of the latter associations to the formation of the Vendian and Early Cambrian clayey rocks.

Abstract
The crystalline complexes of the Hercynian South Altai Metamorphic Belt (SAMB), which is a part of the Central Asian Foldbelt more than 1500 km long. They compose different-scale tectonic plates, the level of metamorphism in which at the early stages reached the conditions of high-temperature amphibolite subfacies and, in places, granulite facies. In terms of tectonics, the band of their outcrops is confined to the margin of the North Asian Caledonian continent, stretching from southeast to northwest along the southern slope of the Gobi, Mongolian, and Chinese Altai to Eastern Kazakhstan, where they are represented in the Irtysh shear zone. The SAMB includes poly- and monometamorphic complexes. The age of granitoids formed at the late episode of metamorphism was determined for the Tsel tectonic plate of the Gobi Altai in the southeastern part of the SAMB: from 374 ± 2 to 360 ± 5 Ma. These and previously obtained results show that the early stage of low-pressure metamorphism and the late stage of high-pressure metamorphism occurred in the age intervals of ~390–385 and 375–360 Ma, respectively, almost throughout this belt. A short-term stage of stabilization was between these stages. These processes occurred during the closure of the basin with the Tethys-type oceanic crust of the South Mongolian Ocean (paleo-Tethys I). The spatial position of the SAMB is determined by the asymmetric structure of the basin, in which the active continental margin is represented along its northern part, and the passive one is represented along the southern one (in modern coordinates).
摘要 海西南阿尔泰变质带（SAMB）是中亚褶皱带的一部分，全长超过 1500 公里。它们组成了不同规模的构造板块，其变质程度在早期阶段达到了高温闪长岩亚相的条件，在某些地方还出现了花岗岩面。从构造上看，它们的出露带仅限于北亚加里东大陆边缘，从东南向西北沿戈壁南坡、蒙古和中国阿尔泰一直延伸到哈萨克斯坦东部，在那里以额尔齐斯剪切带为代表。SAMB包括多变质和单变质复合体。根据测定，在萨马拉盆地东南部戈壁阿尔泰的策勒构造板块变质作用晚期形成的花岗岩的年龄为：374 ± 2 至 360 ± 5 Ma。这些结果和之前获得的结果表明，低压变质的早期阶段和高压变质的晚期阶段分别发生在 ~390-385 Ma 和 375-360 Ma 的年龄段，几乎遍及整个带。在这两个阶段之间有一个短期的稳定阶段。这些过程发生在盆地与南蒙古洋（古特提斯I期）特提斯型洋壳闭合期间。SAMB的空间位置是由盆地的非对称结构决定的，其中活跃的大陆边缘位于盆地北部，而被动的大陆边缘位于盆地南部（按现代坐标）。

Abstract
In the 1970s, the geological mapping in Northeast Asia, in the Ul’ya–Urak interfluve was undertaken by the Aerogeologiya research and production enterprise, while E.L. Lebedev, an employee of the Geological Institute, USSR Academy of Sciences, collected plant fossils. Together with geologists of that enterprise, he developed a new stratigraphic chart of the region, which turned out to be incorrect, as appeared later, being based on ideas on the floral development in the mid-Cretaceous time. Lebedev made vast collections that include several thousand remains of ancient plants. However, this material turned out to be attributed to nonexistent stratigraphic units. This made it of little use for further study. Our investigation has demonstrated that the most representative collections made by Lebedev in the Ul’ya–Urak interfluve (taphofloras of the sites 101 and 107–110, 28, 20, 25, 27, 70–78, 153, 154) come from the first sequence of felsic volcanics of the homodromous succession of volcanism in the Okhotsk–Chukotka Volcanogenic Belt. In the Ul’ya Trough, this sequence was initially called the Amka Formation. It is shown that the previously collected palaeofloristic material is quite representative and in general is of a good preservation. In the future, it could be monographically studied and described as a large regional palaeofloristic and phytostratigraphic object—the Ul’ya flora.

Abstract
On the basis of the mineralogical-petrographic and geochemical study of igneous rocks of intermediate composition of the Pripyat complex of the Late Devonian Pripyat–Dnieper magmatism area, two subphases of the Pripyat magmatism phase have been distinguished: late Fransian (Chernin or Skolodino–Chernin) with potassium specification and early Famennian (Turov–Drozdov (Yelets)) with potassium-sodium specification. For the first time, the U–Pb age of titanite from trachyandesites of the parametric Pribor borehole was estimated for rocks of Pripyat–Dnieper magmatism area at 364 ± 1 Ma. These data confirm the Famennian age of the Yelets subphase of the Pripyat phase of magmatism and make it possible to estimate the duration of the magmatic activity of this structure at least 14 m.y. taking into account the isotope dating of the earliest phases of magmatism in the Pripyat–Dnieper–Donetsk Paleorift Structure as 388 ± 12, 383.3 ± 3.8, 384.7 ± 3.9, and 383.6 ± 4.4 Ma in the Azov Region and 381 ± 2 Ma in the Pripyat–Dnieper magmatism area.

Abstract
The results of a comprehensive study of the Upper Cenozoic Ulan-Zhalga reference section in western Transbaikalia are presented. The paleontological, paleomagnetic and petromagnetic, lithological-mineralogical, and geochemical data obtained allowed us to identify and characterize the Lower, Middle, and Upper Pleistocene and Holocene deposits in the section and to reveal the features and conditions of sedimentation. Five members recognized in the section are combined into two sequences: the lower (Beds 1–27, units 1–3) and the upper (Beds 28–35, units 4–5). The boundary between Matuyama and Brunhes chrons (0.773 Ma) is determined at a depth of 15 m and the upper boundary of the Jaramillo subchron (0.990 Ma) is determined at a depth of 23 m. The Matuyama/Brunhes boundary coincides with the boundary of Lower and Middle Pleistocene faunal assemblages. The formation of the section corresponds to two major stages of sedimentation with the boundary between the units 3 and 4 (depth of 11.8 m). Changes in rock magnetic and grain size parameters through the section has a climatic nature and reflects environmental changes. The formation of the lower part of the section (unit 1), which was accompanied by active soil formation, is characterized by the most heat- and moisture-enriched conditions. The upper sequence of the section accumulated under colder and drier conditions with increased dynamics of aeolian processes.

Abstract
Benthic foraminifera, carbonate microfacies identification, and geochemical analysis of the Permian intervals of Pleshet-1 and David-1 boreholes from western Israel,-allowed a determination of their time frame and tectono-sedimentary relationships, further allowing insights about the nature and regional subsurface expression of the Permian. Carbonate horizons within the mixed lithology successions, yielded foraminifera suggesting the Middle/Late Permian transition. The carbonate microfacies and related stable isotopic profiles indicate a change from siliciclastic marginal marine conditions (Saad Fm.) to fully marine platform conditions (Arqov Fm.) in a gradual marine transgression onto a segmented peneplain, and producing sedimentary facies belts striking SW–NE. A comparison of this work with previous work in southern and eastern Israel suggests that the Permian formations in Israel formed NW to SE diachronistically, by marine transgression during the Middle and the Late Permian, with maximum flooding during the Changhsingian. It appears that although not precisely defined, the regional Middle/Late Permian transition happened during a major marine transgression, characterized by a negative to positive stable isotope shift, and by apparently gradual aridization of the hinterland. The regional onset of sedimentation occurred on a marginally superficially downfaulted northwestward peneplain, subdivided tentatively into four segments with shallow half-graben structures. The three eastern segments ceased their differential movements and maintained uniform northwestward subsidence during the late Wuchiapingian–Changhsingian. The most western fourth segment had differential fault activity through the Triassic and the Jurassic, and is proposed to be placed on a transition to a proximal tectonic necking zone.

Abstract
The Zaisan Depression is a unique geological structure that preserves the most complete sedimentary record of the Late Mesozoic and most of the Cenozoic. A century of studies brought very rich data on the stratigraphy and geological history of the Zaisan sedimentary sequence. The recent scientific progress made it possible to refine the Cenozoic stratigraphic scale of the region. This paper presents the results of a detailed morphostructural analysis and proposes morphotectonic zoning of the Zaisan Depression based on the modern tectonic and geodynamic concepts. New data on magnetostratigraphic subdivision of the Kalmakpai stratotype section, the most complete section of the sedimentary strata of the Zaisan Depression, and on its correlation with the drilling data of its axial part are presented. By the synthesis of magnetostratigraphy with the rich regional biostratigraphic record, the stratigraphy of the region, the dynamics of tectonic movements, and the development of topography and landscapes of the Zaisan Depression and the framing high-mountain structures of Saur-Tarbagatai during the Cenozoic are clarified.

By the synthesis of magnetostratigraphy with the rich regional biostratigraphic record, the stratigraphy of the region, the dynamics of tectonic movements, and the development of topography and landscapes of the Zaisan Depression and the framing high-mountain structures of Saur-Tarbagatai during the Cenozoic are clarified.</p>","PeriodicalId":51168,"journal":{"name":"Stratigraphy and Geological Correlation","volume":"117 2","pages":""},"PeriodicalIF":1.0,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138527404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
