Th-rich Ioparite from the Khibina alkaline complex, Kola Peninsula: isomorphism and paragenesis
Th-rich (up to 18.4 wt.% ThO2) loparite occurs as an accessory phase in foyaite pegmatites at Mr. Eveslogchorr, Khibina complex, Russia. It is associated with aegirine, astrophyllite, eudialyte, lorenzenite, lamprophyllite, magnesio-arfvedsonite and gerasimovskite. Loparite crystals are zoned from niobian loparite (core) to niobian thorian and thorian niobian loparite (rim). Th-enrichment is ac...
متن کاملMicro- and Nano-scale Graphite Cones and Tubes from Hackman Valley, Kola Peninsula, Russia
Several unusual forms of natural graphite from an alkaline pegmatite that crosscuts rischorrite in the Hackman Valley, Khibiny Massif, Kola Peninsula, Russia are described. The graphite occurs macroscopically in two forms: as spherical aggregates up to 2 cm in diameter of friable, radially-aligned fibers ~20 μm in cross section, and as finegrained surface coatings in cavities covering aegirine,...
متن کاملSolar and Wastewater Effects on Zooplankton Communities of the Imandra Lake (Kola Peninsula, Russia), 1990 to 2003
Both heliophysical and anthropogenic (wastewater) effects on zooplankton biomass and abundance of the Imandra Lake (the largest subarctic lake at Kola Peninsula, Russia) were investigated during the 1990 - 2003 period. We used different indexes of solar activity (sunspot numbers and UV- radiation values) as heliophysical factors. Information about UV- radiation values was derived from satellite...
متن کاملFeldspar and Nepheline Syenite Potential in British Columbia
Feldspathic materials are used in the glass and ceramic industries as a source of alkalis, alumina and silica. These elements affect the rate and temperature of melting. fluidity of the melt and physical properties of the finished product. Silica, sodium, potassium and alumina ratios in the feldspar product vary for each industrial user, however, iron must be limited to less than 0. I per cent ...
متن کاملWater- and Boron-Rich Melt Inclusions in Quartz from the Malkhan Pegmatite, Transbaikalia, Russia
In this paper we show that the pegmatite-forming processes responsible for the formation of the Malkhan pegmatites started at magmatic temperatures around 720 °C. The primary melts or supercritical fluids were very waterand boron-rich (maximum values of about 10% (g/g) B2O3) and over the temperature interval from 720 to 600 °C formed a pseudobinary solvus, indicated by the coexistence of two ty...
