Composition of rock



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 0,2 4,0 2,5 1,2 0,3 0,2 1,5 1,2 30,0 1,7

Composition of rock in Zazhoginskoye deposit is rather по составу. The sum (C+SiO2) makes about 83 - 88%
