BURBANKITE GROUP MINERALS AND THEIR ALTERATION IN RARE EARTH CARBONATITES-SOURCE OF ELEMENTS AND FLUIDS (EVIDENCE FROM C-O AND SR-ND ISOTOPIC DATA)

Zaitsev A.N.; Demény A.; Sindern S.; Wall F. (2002)

The 370–380 Ma Khibina and Vuoriyarvi complexes on the Kola Peninsula, Russia, which form part of the Palaeozoic Kola Alkaline Province, contain REE-rich carbonatites with burbankite (Na,Ca)3(Sr,Ca,REE,Ba)3(CO3)5 or ...
CALCITE - AMPHIBOLE - CLINOPYROXENE ROCK FROM THE AFRIKANDA COMPLEX, KOLA PENINSULA, RUSSIA: MINERALOGY AND A POSSIBLE LINK TO CARBONATITES. II. OXYSALT MINERALS

Zaitsev A.N.; Chakhmouradian A.R. (2002)

Carbonate – amphibole – clinopyroxene rocks and carbonatites from the Afrikanda complex, in the Kola Peninsula, Russia, contain a number of oxysalt minerals, including major calcite (15–95 vol.%), subordinate hydroxylapatite, ...
CALCITE - AMPHIBOLE - CLINOPYROXENE ROCK FROM THE AFRIKANDA, KOLA PENINSULA, RUSSIA: MINERALOGY AND A POSSIBLE LINK TO CARBONATITES. III. SILICATE MINERALS

Chakhmouradian A.R.; Zaitsev A.N. (2002)

A calcite - amphibole - clinopyroxene rock (CAPR) occurs as branching veins and segregations in ultramafic alkaline lithologies of the Afrikanda complex, Kola Peninsula, in Russia. The rock is composed predominantly of ...
KUKHARENKOITE-(CE), BA2CE(CO3)3F, A NEW MINERAL FROM KOLA PENINSULA, RUSSIA, AND QUEBEC, CANADA

Zaitsev A.N.; Yakovenchuk V.N.; Chao G.Y.; Gault R.A.; Subbotin V.V.; Pakhomosky Y.A.; Bogdanova A.N. (1996)

Kukharenkoite-(Ce), ideally Ba2Ce(CO3)3F, is a new rare-earth fluorocarbonate mineral, occurring as an accessory mineral in the late REE-carbonatites and REE-rich carbonate-zeolite rocks of the Khibina massif, Kola peninsula, ...
MINERALOGY AND GEOCHEMISTRY OF SILICATE DYKE ROCKS ASSOCIATED WITH CARBONATITES FROM THE KHIBINA COMPLEX (KOLA, RUSSIA) - ISOTOPE CONSTRAINTS ON GENESIS AND SMALL-SCALE MANTLE SOURCES

Sindern S.; Kramm U.; Zaitsev A.N.; Demény A.; Bell K.; Rukhlov A.S.; Chakmouradian A.R.; Moutte J. (2004)

The eastern part of the agpaitic Khibina complex is characterized by the occurrence of dykes of various alkali silicate rocks and carbonatites. Of these, picrite, monchiquite, nephelinite and phonolite have been studied ...
PRECISE GEOCHRONOLOGY OF PHOSCORITES AND CARBONATITES: THE CRITICAL ROLE OF U-SERIES DISEQUILIBRIUM IN AGE INTERPRETATIONS

Amelin Y.; Zaitsev A.N. (2002)

We present the results of a comparative study of several geochronometer minerals (baddeleyite, zircon, apatite, phlogopite and tetraferriphlogopite) and isotopic systems (U-Pb, Th-Pb and Rb-Sr) from phoscorites ...
REE-SR-BA MINERALS FROM THE KHIBINA CARBONATITES, KOLA PENINSULA, RUSSIA: THEIR MINERALOGY, PARAGENESIS AND EVOLUTION

Zaitsev A.N.; Wall F.; Le Bas M.J. (1998)

Carbonatites from the Khibina Alkaline Massif (360–380 Ma), Kola Peninsula, Russia, contain one of the most diverse assemblages of REE minerals described thus far from carbonatites and provide an excellent opportunity to ...
