Abstract:

Purpose.To find out regularities of formation and spatial distribution of new non-conventional types of rare metal mineralization, to develop forecasting and search criteria and to evaluate perspectives as an additional reserve for strengthening and developing East Kazakhstan region mineral resources base.

Methodology. Using ICP MS methods at D.Serikbayev EKSTU Advanced Development Center, there are studied conventional and unconventional plays and occurrences of rare-metal mineralization within the Western Kalba and Rudny Altai, magmatites of Kalba-Narymsky rare-metal granitoid belt. Study on chemical composition of magmatites of a number of intrusive complexes was carried out, the relation of the granitoids with rare metals deposits and manifestations was established. A comparative characteristics of ore mineralization in studied deposits was carried out by scanning electron microscopy (JSM 6390LV).

Findings. Magmatic complexes of potential various rare-metal mineralization within the Kalba–Narym granitoid belt (East Kazakhstan) were identified; conclusions about the relation of potential ore content with granites of certain formation types were made.

Originality. It is established that along with the conventional rare-metal type within the Kalba–Narym metallogenic belt there are found non-pegmatitic unconventional manifestations of rare-metal mineralization of Nb, Li, Sn. Rare-metal pegmatitic ores with the increased content of Li, Ta, Nb, as well as greisen-silica-veined manifestations of Sn, W and gold ore sites with with the increased content of rare elements are to be prospective. The high content of rare metals and rare earth in ores of gold ore deposits of the Western Kalba and Rudny Altai was established.

Practical value. The obtained data can be used for rare metal deposits and complex gold-rare metal deposits prognosis and prospecting.
