Rare earth elements - yttrium and fifteen chemically similar elements from lanthanum to lutetium - can be found in ore minerals of rare metal deposits in Kazakhstan. Therefore, their concentration and form of inclusion in the main ore minerals are of great scientific and practical interest. N.L. Radenko analysed the micro-trace composition of scheelites and wolframites from beds of different formations and genetic types. In this article, we report the specifics of the inclusion of rare earth elements in ore minerals from the rare metal deposit in Bayan (Northern Kazakhstan via simulations (computer and mathematical and thermobarogeochemical studies (by the temperature of the mineral formation. Furthermore, we created a geographic information system of the studied deposit and the 2D and 3D models representing the distributions of the contents of tungsten trioxide between all exploration profiles (2D and along the whole mineralisation volume. Furthermore, the specifics of the tungsten trioxide distribution in the 3D space, particularly in vein-stockwork ore bodies, were studied. This investigation has an influence on the concentration of rare earth elements and has led to a study of the issue of the condition of the formation of ore minerals from the geochemical and thermobarogeochemical points of view, using the results of actual materials and mathematical simulations of the estimation of the heat conditions of the ore-localising environment. As a result, the causeand- effect aspects of the change of the composition of wolframites in stockwork ore bodies are disclosed for this deposit, and scientifically-based information was obtained for the determination of the factors of inclusion of rare types of earth elements in scheelites from the Bayan deposit.
