Lithium Kolmozero deposit of rare metal pegmatites: New data on rare element composition (Kola Peninsula)
The article is devoted to studies the rare element composition of albite-spodumene pegmatites of the lithium with associated Be, Nb, Ta Kolmozero deposit. It is located in the Neoarchaean metagabbro-anorthozites Patchemvareksky massif in the junction zone of the two major regional structures Archaea...

The article is devoted to studies the rare element composition of albite-spodumene pegmatites of the lithium with associated Be, Nb, Ta Kolmozero deposit. It is located in the Neoarchaean metagabbro-anorthozites Patchemvareksky massif in the junction zone of the two major regional structures Archaean age, i.e. the Murmansk block and the Kolmozero-Voron’ya Greenstone Belt of the Kola region. The albite-spodumene pegmatites are identified to be rich in highly incompatible ore elements, i.e. Li, Ta, Nb and Be, depleted by large-ion lithophile elements (Ba ≤ 20 ppm; Sr ≤ 15.4 ppm) and high field strength elements (Y≤ 0.46 ppm, Th ≤ 2.5 ppm, ∑REE ≤ 3 ppm). They are characterized by low indexes of fractioning (Mg/Li ≤ 0.05, Zr/Hf ≤ 7.4) and a high index of rare metal content (Ir = 167321). It may be used as criteria for estimating the commercial potential of the pegmatites regarding their rare metal mineralization. The feldspar (beryllium-bearing) and muscovite-feldspar (beryllium-niobium-tantalum) pegmatites jointed with the Kolmozero deposit have rare metal mineralization and, like albite-spodumene pegmatites, are rich in Li, Nb, Ta, Be, Rb and depleted by Sr, Ва , Y, REE. |
