Abstract

The article is devoted to the study of the rare metal ore occurrence Krasny Kordon, located in the Asubulak ore field (East Kazakhstan), which is part of the Kalba-Narym granitoid belt. The object is confined to the southern rare metal band controlled by the sublatitudinal Asubulak deep fault and is associated with albite-spodumene pegmatites forming the upper zones of the ore column. Based on field studies, analysis of mineral composition and geochemical data (Li, Ta, Nb, Sn, Cs, Rb), patterns of distribution of rare elements in pegmatite veins have been identified. Abnormally high concentrations of lithium, tantalum, niobium, tin, and caesium associated with lepidolite, spodumene, and pollucite have been found. The structural and morphological features of the veins, their zonation and analogy with the industrial Jubilee deposit indicate the high potential of the facility. The necessity of in-depth exploration to assess hidden ore bodies and transfer ore occurrence to the category of industrial deposits is substantiated. The results of the work are relevant for the development of the mineral resource base of rare metals in Kazakhstan
