This article focuses on zircon U-Pb isotope dating and a whole-rock elemental analysis of granodiorites, monzonitic granites, granodioritic porphyries, and alkali feldspar granites in the Yangmugang area of the Lesser Xing’an–Zhangguangcai Range. The zircon U-Pb isotope-dating results revealed that these granitic rocks formed during the late Early ...

Ion-adsorption rare-earth deposits supply over 90% of the global market’s heavy rare-earth elements (HREEs). The genesis of these deposits, particularly HREE deposits, has garnered significant attention. To elucidate the metallogenic mechanisms of HREE deposits, a comprehensive study of the weathering profile of granite was conducted in Jiangxi Pro...

In recent years, Cu-Ni deposits have been discovered at different localities in the Eastern part of the Kunlun orogenic belt such as Xiarihamu, Langmuri, Shitoukengde, and Wenquan. Eclogites are usually exposed in the areas associated with these deposits, thereby implying a certain coupling relationship between the Cu-Ni deposits and eclogite distr...

The Achemmach region is located 40 km to the SW from Meknes city and 6 km to the NE frm the Hammam mine. It is part of the Paleozoic massif of Central Morocco. The studied area is formed by two Paleozoic rock-types: (i) a meta-sedimentary sequence composed of Middle Visean limestone and shale-sandstone withflyschoid of Upper Visean-Namurian age, an...

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...

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...
