About shungite that we sell
Karelia is not only a land of forests and lakes, it's also a place where the unique, the only in the world, deposit of the natural mineral shungite is situated.
Shungite is an earth mineral of black colour with plumbagine gleam.
Shungite is called after a settlement Shunga that is in Karelia. This mineral electroconductive, adsorbtion active and has a bactericidal effect
According to some sourses shungite is 2 billion years old and the main shungite stock is on the territory of Zaonezhski peninsula and around the northern end of Onega lake. By now one Zagozhinskoe deposit with a 35 mln ton stock has been explored.
Schungite is used as a filter element in water filters as well as for producing medical and souvenir goods.
Zazhoginskoye deposit is represented by shungite rock of the following composition:
Main components:
carbon....................................................30
quartz.....................................................45
composite silicates (micas, chlorites)..................20
sulphates.................................................3
Chemical composition (mass %):
SiO2 | TiO2 | Ai2O3 | FeO | MgO | CaO | Na2O | K2O | S | C | H2O |
57 | 0,2 | 4 | 2,5 | 1,2 | 0,3 | 0,2 | 1,5 | 1,2 | 30 | 1,7 |
Composition of rock in Zazhoginskoye deposit is rather composition. The sum (C+SiO2) makes about 83 - 88%
