The exposition also shows many differently-colored types of tourmaline from the Urals, Pamirs, Baikal and other regions. Druses of green crystals of dioptase (copper emerald) from the Middle Asia and crimson-red eudialyte disseminations of alkali magmatic rocks from the Kola Peninsular are of special interest.

The subclass of silicates, characterized by chain crystal structure, is represented in Mineralogy Section by all the main groups of pyroxenes and amphiboles. Polished lumps of the second important gem from the Urals, rhodonite from Sedelnikovo Deposit, and samples of differently-colored nephrite from the Eastern Sayan and Baikal region have extraordinary decorative qualities.

Laminated silicates of the exposition are represented by a big group of micas. The most impressive are gigantic crystals of colorless muscovite (1000 x 1000 mm) from the Mamsky mica-bearing region of Siberia and scurfy aggregates of lilac lepidolite from pegmatitic veins of the Pamirs. The Urals region in the stall of laminated silicates is represented by numerous multi-colored types of serpentine (zmeyevik), sheet talc crystals and chlorite. The museum has several samples of charoite from the Murun land mass of the Eastern Siberia, a nice gem-stone, discovered in the 1970s.

The exhibited tectosilicates of Mineralogy Section demonstrate all the main groups of the subclass mineral: feld spars, feldspathoids and zeolites. As rare samples one should mention wonderful lumps from pegmatitic vein cavities from Murzinka, Mokrusha, Alabashka, and Ilmen deposits. Rather interesting are samples of plagioclases with moonstone effect (irisation) such as labradoritites from Canada, Ukraine, and Kalarsky anorthosite land mass of Siberia and moonstones from Karelia.

The most interesting among feldspathoids are blue lazurites from deposits of Baikal region, the Pamirs and Afganistan. A separate stall of the exhibition is dedicated to remarkable useful minerals, zeolites from Kamchatka, Caucasus, Siberia and other areas. Here one can see zeolite-bearing rocks, which were discovered in Drozhzhanovsky District of Tatarstan not long ago.

There is an interesting story, which unites silicates, Kazan Emperor University and German citizen Wagner. Wagner graduated from Derpthe University in 1818 with a degree of chemist. In 1826 he got a degree of doctor at Willen University, worked at Bogoslovsk Plant and then at Verkhneisetsk Plant in the Urals. Wagner was conferred Doctor's degree for his medical work and tried to get fixed up in a job at the Surgery Department of Willen University, but failed.

Staying in the Urals, Wagner got interested in minerals, found and described a black epidote, and named it "pushkinite" after the warden of Kazan University Count Musin-Pushkin. Due to the fact Wagner was appointed the Head of Mineralogy Department of the Kazan Emperor University in 1840.
