SOURCES OF THE PALEOZOIC SEDIMENTARY ROCKS IN THE NORA-SUKHOTINO TERRANE: RESULTS OF Sm-Nd ISOTOPIC-GEOCHEMICAL STUDIES

Autor: Yu. V. Smirnov, S. I. Dril

Publikováno v: Геодинамика и тектонофизика, Vol 14, Iss 6 (2023)

The paper presents the first results on Sm-Nd isotopic-geochemical studies of the Paleozoic sedimentary rocks in the Nora-Sukhotino terrane at the northeastern flank of the South Mongolia-Khingan orogenic belt.According to the studies, the sedimentar

SOURCES AND MECHANISMS OF FORMATION OF ALKALINE RARE-METAL GRANITES AT THE ZASHIKHINSKY MASSIF BASED ON GEOCHEMICAL AND Nd ISOTOPE DATA

Autor: N. V. Alymova, A. A. Vorontsov, S. I. Dril, I. A. Sotnikova

Publikováno v: Геодинамика и тектонофизика, Vol 13, Iss 4 (2022)

The intraplate alkaline-granite magmatism essentially contributes to formation of rare-metal strategic raw materials. In the Major Sayan Fault of the East Sayan Mountains, the rocks of the Zashikhinsky (Pz3) massif were studied through the isotope-ge

TWO STAGES OF THE CENOZOIC ALKALINE-BASALT VOLCANISM IN THE DARKHAD DEPRESSION (NORTHERN MONGOLIA) – GEOCHRONOLOGY, GEOCHEMISTRY, AND GEODYNAMIC CONSEQUENCES

Autor: S. S. Tsypukova, A. B. Perepelov, E. I. Demonterova, A. V. Ivanov, S. I. Dril, M. I. Kuzmin, A. V. Travin, Yu. D. Shcherbakov, M. Yu. Puzankov, S. V. Kanakin

Publikováno v: Геодинамика и тектонофизика, Vol 13, Iss 3 (2022)

The isotopic data showed that there are two stages distinguished in the Cenozoic history of the Darkhad depression volcanic activity, the Late Oligocene initial stage (~28.0–26.6 Ma) and the final Late Miocene – Early Pliocene stage (~5.8–4.2 M

AGE AND COMPOSITION OF THE EARLY PALEOZOIC MAGMATIC ASSOCIATIONS AND RELATED RARE-ELEMENT PEGMATITES IN THE SOUTH-EASTERN PART OF THE SANGILEN BLOCK, TUVA-MONGOLIAN MASSIF

Autor: L. G. Kuznetsova, S. P. Shokalsky, S. A. Sergeev, S. I. Dril

Publikováno v: Geodinamika i Tektonofizika, Vol 12, Iss 2, Pp 261-286 (2021)

The article presents new data on ages (U-Pb zircon dating, SIMS SHRIMP-II) and chemical compositions of rocks from gabbro-granitic and granite-leucogranitic magmatic associations. These rocks preceded the formation of Li-enriched spodumene pegmatites

Mineralogy, Geochemistry, and Sr–Nd–Pb Isotope Systematics of Late Cenozoic Basanites of the Borozdin Bald Mountain (Khentei Ridge, Southern Transbaikalia)

Autor: Elena I. Demonterova, A.A. Karimov, A.Ya. Medvedev, V.A. Belyaev, Alexander V. Ivanov, M.A. Gornova, S. I. Dril

Publikováno v: Russian Geology and Geophysics. 61:838-857

—We have estimated the P–T conditions of formation of basaltoid melts: P = 1.15–1.06 GPa and T = 1379–1293 ºC. Olivine pyroxenites (Ol + Cpx + Grt) are assumed to be a mantle source for nepheline-normative basanitic melts. During ascent, the
