Oil and Gas Systems, Coal Are Components of Hydrocarbon Sphere of the Earth

Abstract

Comparison of elemental compositions of oil, coal and biomaterial has shown that a source of oil and gas systems and coal is mainly not biomass, but the deep abiogenic hightemperature fluids representing a mixture of light hydrocarbon, sulfur, metal-containing structures, etc. In the course of the fluids movement towards the Earth’s surface, hydrocarbon under catalytic action of sulfur and metals undergoes polycondensation transformations to afford hydrocarbons of various types and molecular mass, sulfur- and organometallic compounds. Formation of a hydrocarbon system depends on a structure of the fluid.
