The Late Paleozoic–Early Mesozoic Mongol-Okhotsk Ocean extended between the Siberian and Amur–North China continents. timing modalities of oceanic closure are widely discussed. It is largely accepted that ocean closed in a scissor-like manner from southwest to northeast (in modern coordinates), though this process remains uncertain. Recent studies have shown both western (West Transbaikalia) eastern (Dzhagda) parts almost simultaneously at Early–Middle Jurassic boundary. However, little...
Herein we report the results of LA-ICP-MS dating detrital zircons from eight stratigraphic levels Proterozoic section Igarka uplift (northwestern Siberian Platform). The age spectra include Meso- and Neoarchean (3100–2600 Ma), Paleoproterozoic (2100–1700 Ma) Neoproterozoic (1000–600 ages. However, distribution drastically varies among samples. zircons, associated with hypothetic orogenic belt at platform periphery, dominate in lowstand system-tract continental marginal marine strata...
The publication presents the first results of geochemical and U–Th–Pb (LA–ICP–MS) isotope studies on terrigenous deposits allegedly Lower-Middle Devonian siltstone-sandstone sequence Kamenushka River basin Zeya-Selemdzha fragment Nora-Sukhotino terrane. It has been found that sandstones we studied correspond in their characteristics to sediments formed a setting an active continental margin or island arc, with acidic intermediate igneous rocks minor recycled (second cycle) material being...
Our study investigates a possibility of using isotope ratios U‐Th‐Pb system in zircon analysis by the LA‐ICP‐MS technique and monitoring precision, convergence accuracy. New U‐Pb isotope‐geochronological data has been obtained for salic mafic members bimodal Late Paleozoic series subparallel dykes central part Western Transbaikalia. It is shown that (290–280 Ma) gives evi‐ dence extension continental crust at final stage granitoid magmatism. Similar ages zircons subvolcanic rocks confirm...
The Mesozoic geodynamic evolution of Transbaikalia has been largely controlled by the scissors-like closure Mongol–Okhotsk Ocean that separated Siberia from Mongolia–North China continents. Following oceanic closure, tectonic region was characterized collisional uplift and subsequent extension gave rise to formation metamorphic core complexes. This complex setting prevailed simultaneously between 150 Ma 110 both in Transbaikalia, North Mongolia, within Craton. Published paleobotanical...

The article discusses the composition of studied ore-forming solutions and P-T conditions molybdenum mineralization in Pervomaisky stockwork deposit which is situated within Dzhidinsky ore field (South-Western Transbaikalia, Russia). New geochronological data zircons from granites, muscovite, molybdenite zones indicates association granite formation deposition processes occurred 119–128 million years ago. Quartz-molybdenite veins were formed at temperature ≥314–186 °C with some boiling...
Research subject . Upper Precambrian metaterrigenous deposits of the northern part Lyapinsky anticlinorium in Subpolar Urals. Material and methods From rocks section different stratigraphic levels, monofractions zircons were isolated their optical isotope-geochronological (U-Pb LA-SF-ICPMS) studies performed. Results. Age boundaries formation Puivinskaya, Khobeinskaya, Moroinskaya Formations Urals specified. A comparison was carried out age populations detrital from terrigenous sequences...
