Global implication of mesoproterozoic (~ 1.4 Ga) magmatism within the Sette-Daban Range (Southeast Siberia) [PDF]

open access: yesScientific Reports, 2021
Mesoproterozoic period included several global tectonic events like break-up of Nuna and formation of Rodinia. However, although Siberia is a significant piece of both supercontinents, Mesoproterozoic time is marked by quiescence of magmatic and tectonic

THE EARLY PALEOZOIC BASITE MAGMATISM IN THE NORTHEASTERN SIBERIAN CRATON

open access: yesГеодинамика и тектонофизика, 2016
The Early Cambrian tectonomagmatic activation is manifested in the northeastern passive margin of the Siberian Craton within the area of the Olenek uplift, as well as in the Kharaulakh segment of the Verkhoyansk fold‐ thrust belt that was thrusted onto ...

FINAL CONSOLIDATION AGE OF THE SOUTHERN PART OF THE SIBERIAN CRATON

open access: yesГеодинамика и тектонофизика, 2023
Petrographic, geochemical and U-Pb geochronological research studies are done into cataclastic granitoids of the southeastern part of the Irkutsk block of the Sharyzhalgay basement uplift of the Siberian craton – the uplift which is considered southern ...

Crustal structure of the Siberian craton and the West Siberian basin: An appraisal of existing seismic data

open access: yesTectonophysics, 2013
AbstractWe present a digital model SibCrust of the crustal structure of the Siberian craton (SC) and the West Siberian basin (WSB), based on all seismic profiles published since 1960 and sampled with a nominal interval of 50km. Data quality is assessed and quantitatively assigned to each profile based on acquisition and interpretation method and ...

Petrogenesis of juvenile pelletal lapilli in ultramafic lamprophyres [PDF]

open access: yesScientific Reports, 2023
The Chadobets alkaline-carbonatite complex (Siberian craton) is a natural laboratory for all varieties of ultramafic lamprophyres, including damtjernites formed by fluid-explosion mechanisms, which contain a large number of pelletal lapilli.

Sedimentary provenance supports a mid-paleozoic tectonic connection between the Junggar and Altai terranes in central Asia [PDF]

open access: yesScientific Reports
The provenance of Precambrian detritus in the Junggar and Altai terranes provides crucial constraints on the peri-Siberian accretionary tectonic evolution in the middle Paleozoic.

THE “CLINOPYROXENE” PALEOGEOTHERM BENEATH THE OBNAZHENNAYA KIMBERLITE PIPE AND THIСKNESS OF LITHOSPHERE UNDER THE KUOYKA FIELD (SIBERIAN CRATON, YAKUTIA)

open access: yesГеодинамика и тектонофизика, 2022
The mantle paleogeotherm under the Obnazhennaya kimberlite pipe (Kuoika field, Siberian craton) was reconstructed using the chemical composition of clinopyroxene xenocrystals and the FITPLOT program.

STRAIN RATES FOR THE SOUTHERN SIBERIAN CRATON DERIVED FROM GPS MEASUREMENTS

open access: yesГеодинамика и тектонофизика, 2022
This paper presents quantitative estimates of the strain rates for the southern part of the Siberian craton derived from GPS data. The obtained results confirmed the theoretical concept of low strain rates (10–9×year–1) in the intra-platform areas.

Eclogite Varieties and Their Positions in the Cratonic Mantle Lithosphere beneath Siberian Craton and Archean Cratons Worldwide

open access: yesMinerals, 2022
The pressure-temperature (PT) conditions and position of different groups of eclogites in the sub-cratonic lithospheric mantle (SCLM) worldwide were established using clinopyroxene Jd-Di and garnet thermobarometry. Beneath Siberia, Fe-eclogites found within the 3.0–4.0 GPa formed in Early Archean times.
