Electron-conductive sulfide- and carbon-bearing structures in the continental earth's crust ("Sc layer by Semenov")

The paper highlights the nature of electron-conductive graphite- and sulfide-bearing anomalies called "SC layer by Semenov" in honor of inventor of this phenomenon – professor of Saint Petersburg University Alexander Sergeevich Semenov. The electrical conductivity of the Earth solid crystalline cover called the lithosphere is determined by two factors to follow: the vertical change of the fluid regime, composition and thermodynamic state of rocks with depth and the horizontal heterogeneity caused by the "crustal" conductivity anomalies of electron-conductive nature mostly. Crustal anomalies strongly affect results of the deep soundings. The formal 1D interpretation presents these as "fictive" intermediate conductive layers at the depth of from a few up to tens of kilometres. Investigations on shields provide a more detailed analysis of their structure, geological position, and value at forecasting mineral resources.
