Ore and Geochemical Specialization and Substance Sources of the Ural and Timan Carbonatite Complexes (Russia): Insights from Trace Element, Rb–Sr, and Sm–Nd Isotope Data
Autor: Irina Nedosekova, Nikolay Vladykin, Oksana Udoratina, Boris Belyatsky
Publikováno v: Minerals, Vol 11, Iss 7, p 711 (2021)
The Ilmeno–Vishnevogorsk (IVC), Buldym, and Chetlassky carbonatite complexes are localized in the folded regions of the Urals and Timan. These complexes differ in geochemical signatures and ore specialization: Nb-deposits of pyrochlore carbonatites

Thermobarometry and Geochemistry of Mantle Xenoliths from Zapolyarnaya Pipe, Upper Muna Field, Yakutia: Implications for Mantle Layering, Interaction with Plume Melts and Diamond Grade
Autor: Igor Ashchepkov, Nikolay Medvedev, Nikolay Vladykin, Alexander Ivanov, Hilary Downes
Publikováno v: Minerals, Vol 10, Iss 9, p 755 (2020)
Minerals from mantle xenoliths in the Zapolyarnaya pipe in the Upper Muna field, Russia and from mineral separates from other large diamondiferous kimberlite pipes in this field (Deimos, Novinka and Komsomolskaya-Magnitnaya) were studied with EPMA an

Trace element geochemistry and isotopy (Sm, Nd) of lamproites of the Aldan Shield
Autor: Nikolay Vladykin, Irina Sotnikova
Lamproites of the Aldan Shield were found (Vladykin 1985) at the beginning of 80-es (for the first time in the USSR), being mainly the intrusive varieties of lamproites, though there occur among them some dyke and volcanic varieties. The general geol

Varieties of eclogites and their positions in the cratonic mantle lithosphere revealed by Jd-Di thermobarometry and trace element geochemistry
Autor: Igor Ashchepkov, Alla Logvinova, Zdislav Spetsius, Theodoros Ntaflos, Hilary Downes, Nikolay Vladykin, Alexander Ivanov
The PT conditions and position of different groups of eclogites in the subcratonic lithospheric mantle (SCLM) worldwide has been established using clinopyroxene Jd-Di thermobarometry for different cratons and kimberlite localities. Beneath Siberia, F
