Abstract
The discovery of a new mineral resource in Karelia-shungite- and the confirmation of the finding in the geological literature have a long history. In 1876, local peasants found black stones near the village of Shun'ga, which were taken to be coal and called Olenets anthracite. A discussion began on the nature of this strange anthracite, which did not burn in furnaces. The found of the Karelian geological school, A.A. Inostrantsev, was the first to doubt that Olenets anthracite was really coal, and he named it shungite. Shungites, very unusual, barely combustible high-carbon rocks, have a variety of potential uses. Although details remain obscure, the authors propose a metasomatic origin involving migration and reduction of carbonaceous compounds driven by igneous intrusions. 10 references.
