The paper presents formulas, which refect the variations in the composition of cassiterite, wolframite (ferberite and hubnerite) and associated minerals (silicates, phosphates, tantaloniobates, sulfdes, etc.) from the Maly Khingan tin deposits (Khingan and Berezovoe), tin-tungsten deposits of the Amur Region (Pravy Urmiy and Merek), and Primorye (Tigrinoe, Ust-Mikulinskoe, Zabytoe, and Shibanovskoe) and, partly, from the Zimnee tin-polymetallic deposit. All studied cassiterite crystals contain a low amount of Ti and Ta, and less often W, Nb, In, and Sc; wolframite locally contains Nb or Nb and Ta.

Keywords: Maly Khingan, Amur region, Primorye, tin and tin-tungsten deposits, cassiterite, wolframite, ferberite, hubnerite, compositional variations.
