RARE METAL POTENTIAL OF SOUTH-EAST KALBA, EASTERN KAZAKHSTAN (AS AN EXAMPLE OF CHERDOYAK DEPOSIT)
Abstract
Rare metals such as Sn, W, Ta, Nb, Li and rare earth elements are essential for modern technologies, renewable energy systems and advanced materials. Their growing demand increases the importance of studying rare-metal provinces and identifying new perspective areas. The Kalba–Narym belt in Eastern Kazakhstan is one of the main rare-metal regions of Central Asia. However, the potential of its south-eastern part remains insufficiently evaluated. This paper considers the Cherdoyak deposit as an example of greisen–quartz vein mineralization formed during multi-stage granite magmatism. The geological and structural setting, geochemical composition of the host rocks, mineralogical composition, and formation model of the Cherdoyak deposit were studied in detail. The results show that pre-Permian Kunush plagiogranites, heavily fractured and altered by subsequent granite intrusion, served as host sites for tin-tungsten mineralization. The obtained data show that the Cherdoyak deposit can be a reference for identifying tin-tungsten mineralization in the southeastern part of the Kalba region.
