Cation ordering, valence states, and symmetry breaking in the crystal-chemically complex mineral chevkinite-(Ce): Recrystallization, transformation, and metamict states in chevkinite
Autor: Ray Macdonald, Marcin Stachowicz, Mark D. Welch, Krzysztof Woźniak, Pavel M. Kartashov, Bogusław Bagiński
Publikováno v: American Mineralogist. 104:1481-1486
Annealing is commonly used in the recrystallization of metamict minerals in an attempt to reconstruct the original structure. Annealing at 750 °C of Nb-rich chevkinite-(Ce) from the Biraya rare-metal deposit, Russia, resulted in the structural trans

Autor: S. S. Bukalov, Т. А. Gornostaeva, L. A. Leites, Pavel M. Kartashov, R. R. Aisin, O. A. Bogatikov, A. V. Mokhov
Publikováno v: Доклады Академии наук. 485:609-613
During studying samples of lunar regolith from samples of the AS “Luna-24” using the methods of Raman spectroscopy, the presence of three structural modifications of carbon was established: amorphous sp2 carbon, shungite-like carbon and turbostra

Ziminaite, Fe3+VO4, a new howardevansite-group mineral from the Bezymyannyi volcano, Kamchatka, Russia
Autor: Igor V. Pekov, Pavel M. Kartashov, Vasiliy O. Yapaskurt, Oleg I. Siidra, Yury S. Polekhovsky
Publikováno v: Mineralogy and Petrology. 112:371-379
The new mineral ziminaite, ideally Fe3+VO4, was found in fumarole sublimates at the Bezymyannyi volcano, Kamchatka, Russia. Ziminaite occurs as lamellar, tabular or flattened prismatic crystals up to 10 × 30 × 50 μm typically epitaxially overgrowi

Behaviour of ThSiO4 during hydrothermal alteration of raremetal rich lithologies from peralkaline rocks
Autor: Pavel M. Kartashov, Bogusław Bagiński, Ray Macdonald, Dmitry Zozulya
Publikováno v: Mineralogical Magazine. 81:873-893
The behaviour of ThSiO4 during low-temperature alteration has significance for element mobility and redistribution. Here we describe five types of alteration of ThSiO4 by hydrothermal fluids: (1) primary ThSiO4 associated with chevkinite-(Ce) in a qu

Publikováno v: European Journal of Mineralogy. 28:789-810
The Keivy peralkaline granite complex, Kola Peninsula, Russia, is the only Archaean A-type granite known in the world. It contains numerous rare-metal occurrences, formed by a complex sequence of magmatic, late magmatic and hydrothermal processes act
