Gamma rays shielding. A layer of shaly shungite provides a more effective level of shielding than equally thick layers of concrete or aluminium.
Shungite shields can be used in the areas of potential ecological disasters, such as oil pipelines, gas-condensate reservoirs, handling grounds for combustible materials, sump and sewage tanks, etc. A promising area of shungite application is seen to be the construction of chemical and radioactive waste storages.

The shungite-bearing rocks were accumulated within a volcanic continental rift setting, in a non-euxinic, brackish-water, lagoonal environment developed on the rifted margin of the Archaean craton. The occurrences of shungite-bearing rocks represent a combination of a petrified oil field, petrified organosiliceous diapirs and oil spills.

Shungite occurs in rocks as 1 mm to 20 cm clasts of lustrous shungite that probably represent redeposited, oxidised oil derived from oil spills.
