Abstract

The article shows the conditions for the formation and existence of both polymorphic modifications of carbon in natural conditions. The formation of diamond and carbon can be realized in the presence of carbon-containing rocks in near-surface and surface reducing conditions with a low partial pressure of oxygen. The formation of explosion tubes is carried out due to a chain reaction between deep hydrogen and oxygen in the air with the release of a huge amount of heat, increasing the temperature to 3000°C during a typical exothermic reaction.
