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

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: Геодинамика и тектонофизика, 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
