Geochemical features of apogranitoid tungsten mineralization (as exemplified by the lower stage of the Yachton deposit)

The article reflects the geochemical features of the apogranoid tungsten mineralization of the lower tier of the Yakhton deposit, which is located in the near-­right part of the Chakylkalyan ridge. 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 silicon­alkaline ore­bearing metasomatites are formed; significant addition of Ca, Si, Mg and Fe to the near­ore space; poly­stage and discrete nature of the ore process; a complexly constructed halo of ore­bearing elements.
