Abstract
The spatial and electrical parameters of natural carbon-containing shungite with different carbon content have been studied by electro-force spectroscopy. The dependence of the conductivity of shungite on the carbon content is determined using volt–ampere characteristics. It is shown that the general behavior of the obtained dependence successfully correlates with similar data obtained by the contact and microwave methods. A model of the shungite structure in the form of carbon granules in a quartz matrix is proposed. It is shown that the carbon concentration of about 40% closest to the experiment corresponds to the model of the closure of cubic granules along the diagonal of the cube face.
