The Crystal Structure and Genesis of the Gold Telluride

The primary gold telluride minerals are represented by three distinct species: calaverite (Au 0. 85Ag 0.15Te 2), krennerite (Au 0. 75Ag 0.25Te 2), and sylvanite (AuAgTe 4). All three of these mineral species are historically important ores of gold (and to a lesser extent silver), and are found in relative abundance within several of the world’s major telluride districts.
