Abstract. The article describes new types of tungsten mineralization for the Chakylkalyan-Karatube mining region, the main features of which are: aluminosilicate (granitoid) substrate, along which silicon-alkaline ore-bearing metasomatites are formed; significant addition of Ca, Si, Mg and Fe to the near-ore space; poly-stage and discrete nature of the ore process; a complexly constructed halo of ore-bearing elements. Of particular importance for understanding the geological structure and metallogeny of the central part of the Chakylkalyan megablock are products of alkaline-basalt magmatism, which make up the Early Mesozoic formation of trachydolerites and camptomonchits, which form single dikes on the Yakhton ore field, and in neighboring territories of southern Uzbekistan and diatrums and diatrums.
