AbstractIn the Angara part of the Yenisei Ridge, a sequential section of the metapicrite–basalt sequence and the overlying carbonate rocks of the Gorevskaya suite has been established, which is considered as a single volcanogenic–sedimentary complex formed at the turn of the Late Mesoproterozoic and Early Neoproterozoic in the riftogenic continenta...

Abstract—This article describes the geological structure of the Sarsangi gabbro–diorite–plagiogranite complex located in the boundary zone between the Middle and South Urals. The formation of its massifs took place in the Late Silurian in the abyssal zone at approximately 6.5–7.0 km. The temperature ranges of crystallization of granodiorites and ga...

In the Angara part of the Yenisei Ridge, a sequential section of the metapicritic–basalt sequence and overlying carbonate rocks of the Gorevskaya Formation is established. This section is considered as a single volcanic–sedimentary complex formed at the Late Mesoproterozoic–Early Neoproterozoic boundary in the riftogenic marginal–continental paleob...

AbstractThe Siratur gold deposit occurs in the northern part of the South Uralian segment of the Main Uralian Fault. The ore zone of the deposit is confined to an area of a tectonic junction of serpentinites of the Nurali massif and a longitudinal band of carbonaceous schists of the Ordovician Polyakovka Formation, which also hosts abundant basalts...

Abstract—The paper presents detailed data on the mineralogy, chemical composition, geothermobarometry, and U–Pb zircon isotopic dating of peraluminous sapphirine-bearing crystalline schists, which occur in association with biotite–garnet–sillimanite gneisses, hypersthene–plagioclase–potassic feldspar and high-K hypersthene orthogneisses, and Ti-ric...

AbstractMagmatic rock plays a key role in controlling tectonics. By determining the chronology, petrogenesis and tectonic significance of newly discovered granite porphyry and granite units, this study documents the Bangong-Nujiang Neo-Tethys ocean evolution and the tectonic environment of the Zanzongcuo zone. Based on laser ablation inductively co...

The paper considers the role of the lithospheric mantle and asthenosphere during the Late Cenozoic collision volcanism of the Lesser Caucasus. The results of petrogeochemical studies show that the products of volcanism of the West Volcanic Zone of Armenia and the calc-alkaline andesite–dacite–rhyodacite complex of the Neogene Kelbadzhar and Karabak...

The Kiselyovka–Manoma accretionary complex formed at the end of the Early Cretaceous during subduction of the Pacific oceanic plate underneath the Khingan–Okhotsk active continental margin along the east of Eurasia. It is composed of Jurassic–Early Cretaceous oceanic chert, siliceous mudstone, and limestone that include a significant amount of basi...

The Yakchi chert–volcanogenic formation is differentiated at the base of the stratigraphic succession in the Khor-Tormasu subzone of the Central Sikhote-clin structural–formational zone or the Samarka terrane of the Jurassic accretionary prism. The paper considers the results of biostratigraphic study of its deposits and petrogeochemical studies of...

The new data obtained during thorough geological-structural, geochronological, petrographic, and petrochemical investigations of Late Cretaceous granitoids from the southern Sredinnyi Range in Kamchatka and zircon dating by the U-Pb SIMS and LA-ICPMS methods indicate that this region was characterized by intense granitoid magmatism in the Campanian...
