Tetrahedrite is a common cupreous sulfide mineral in the Ashele volcanic massive sulfide deposit. In the main (No.I) orebody, it is characterized by high As content but low Sb, in No.Ⅱorebody, it is characterized by high Sb content but low As; in both orebodies, it is cha_racterized by high Zn content and insignificant temporal and spatial variations of chemical compositions. Compared with other kinds of ore deposits, zinc_tennantite is a kind of typomorphic mineral in the Altai mineralization province and is useful for the exploration of volcanogenic massive sulfide deposits.
