  Définition

  Any mass of unusually abundant metallic sulfide minerals.

  Notes :

  Massive [economic geology]: Said of a mineral deposit (esp. of sulfides) characterized by a great concentration of ore in one place, as opposed to a disseminated or veinlike deposit.
  
  The term "massive" [...] carries no textural connotation. The economic minerals of these ores are predominantly chalcopyrite and/or sphalerite, but most also contain economic concentrations of silver and/or gold and, in post-Archean ores, of galena.
  
  [D.F. Sangster and S.D. Scott] have arbitrarily subdivided the massive sulfide ores into three types: (1) those which are predominantly of volcanic association; (2) those predominantly of sedimentary association and; (3) those of a mixed volcanic and sedimentary association [...].
