Abstract:

Purpose. Studying the patterns of formation and assessing the prospects of non-traditional types of rare-metal mineralization in East Kazakhstan.

Methodology. Analysis of literary and funds materials; conducting field research on typical objects; sample selection; conducting of isotope research on typical objects; ICP-MS – Agilent 7500cx mass spectrometric analysis, microprobe analysis using a JSM 6390LV scanning electron microscope with an energy dispersive attachment, X-ray diffraction analysis — CPB-1M, silicate chemical analysis.

Findings. A new non-traditional “non-pegmatite” type of rare-metal mineralization of predominantly lithium specialization associated with small intrusions and dikes of the kunush complex and albitized and greisenized granites (apogranites) is substantiated.

Originality. A geological and genetic model of rare metal ore formation has been developed, reflecting the superimposition of rare metals (Sn, W, Li, etc.) on earlier small intrusions of plagiogranites of the kunush complex (C₃), susceptible to contact-metasomatic transformations under the influence of rare-metal granites of the Kalba complex (P₁). The prospects of an independent “non-pegmatite” type of tin-tantalum-lithium mineralization are substantiated.

Practical value. The results of the research are aimed at strengthening the mineral resource base as an additional source of rare metals for existing enterprises in East Kazakhstan.
