A Possible Reason for the Predomination of Vanadium in the Microelement Composition of Sulfurous Oils

In accordance with the abiogenic hypothesis of the origin of oil, deposits formed as a result of degassing of the Earth, in particular, due to the interaction of mantle methane and its polycondensation products with elemental sulfur, are thermodynamically open systems. In open systems, self-organization processes are realized and a progressive evolution of the catalyst of the basic reaction occurs, accompanied by an increase in its activity and accumulation in the system. The predominance of vanadium in the trace element composition of sour oils may be due to its catalytic activity in the basic reaction of the formation of C–S bonds.
