Abstract
The temperature dependence of electrical conductivity and the shielding effectiveness of shungites have been studied at temperatures ranging from 77 to 300 K. The idiosyncrasies of temperature dependences for measuring electrical parameters were determined. Correlations of the π + σ plasmon energies with changes in the frequency dependence of shielding effectiveness on temperature were determined.
