Sulphides and Their Analogues

This class includes minerals, which represent compounds of metals and semimetals with sulphur, arsenic, selenium and tellurium. In total the class enumerates more than 25 minerals. The main metals of such compounds are Fe, Cu, Zn, Pb, Co, Ni, Ag and others.


As a rule these minerals are non-transparent or slightly translucent with metallic or brilliant luster. They are of high density and electric conductivity. Many minerals of the class are the most important ores of non-ferrous, precious and rare metals, while sulphide deposits have complex character and are called poly-metallic.


The Mineralogy Section of the KSU Geology Museum has a number of rare exhibits of sulphide minerals. There are remarkable lumps of galena and sphalerite from the famous Far-Eastern Dalnegorskoye Deposit, acicular aggregates of antimonite crystals from Japan, right cubic pyrite crystals from Akchatau deposit in Kazakhstan, and sphere-like concretionary forms of pyrite and marcasite from the Volga Region.


The major part of the sulphides and their analogues are kept in the Museum stores as theme collections on different regions: cupper-nickel sulphide minerals (Norilsk deposits), arsenic compounds (the Caucasus), poly-metal ores (Altai), sulpho-salts and grey ores (the Urals) and others.
