In pyrite, trace elements can be divided into three groups according to the most likely occurrence of the element. Elements that occur as inclusions in chalcopyrite include Pb, Bi, Zn (?), and Ba. Lead, Ba, Sb, possibly, and in some cases, Cu, occur commonly as inclusions in sphalerite. The Se content of pyrite in volcanic-hosted massive sulfide deposits varies as follows: in Cu-poor, Zn-rich deposits, Se levels are low throughout; in Cu-rich deposits, Se levels are highest in stringer zones and the lower part of the massive sulfide lens, and decrease toward the top of the massive sulfide lens and into peripheral altered rocks. -from Authors
