Sphalerite primarily hosts Fe, Cd, Mn, In, Sn, Ga, Co, Hg and Cu, whereas galena hosts Ag, Bi, Sb, Se and Tl. The LA-ICP-MS mapping also shows low levels of As in galena. Modest amounts of Ag are noted in sphalerite.

عرض المزيدSphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear to white crystals (known as Cleiophane). Yellow to orange sphalerite is often called "golden sphalerite." Red shades of sphalerite are known as Ruby Blende or Ruby Jack.
