New data on a zonal structure of the Koupol deposit fahlores grains are given,and features of their chemism are shown.The fahlores chemical composition within the zones evolves from es-sentially arsenious (Fe-tennantite and Zn-tennantite),through mixed fahlores (Zn-tennantite-te-trahedrite arsenious and Zn-tennantite-tetrahedrite antimonous),to essential antimonous (Ag-bearing Zn-tetrahedrite).Varying chemical composition manifested as mineralogical-geochemical zonation of the fahlores grains is caused by changes of physicochemical conditions of the ore forming process during the time.
