GERMANIUM MINERALS IN THE SULFIDE ORES FROM ALEXANDRINSKIY ORE FIELD DEPOSITS
Germanite, renierite, germanocolusite, and argyrodite were described in the ores from Alexandrinka and Babaryk deposits in Alexandrinskiy ore field. Optical and chemical data about these minerals are demonstrated. Minerals associating with germanium minerals is characterized. The conditions of the deposition of germanium in sulfide ores are considered.
