Abstract
В работе дана геологическая характеристика пегматитового тела "Виртаоя". Составлены две геологические схемы строения пегматита. Пегматит отнесен к альбит-сподуменовому типу. Изучен химический и минеральный состав пегматита, в частности минералы тяжелой фракции, с помощью рентгеноспектрального микроанализа и ICP-MS.
The work provides a geological characteristic of the pegmatite body "Virtaoya". Two geological diagrams of the structure of pegmatite have been compiled. Pegmatite is classified as an albite-spodumene type. The chemical and mineral composition of pegmatite, in particular heavy fraction minerals, was studied using X-ray spectral microanalysis and ICP-MS.
