A possible mechanism for natural graphite formation ...

By extrapolating the Arrhenius plots for carbonization and experimental thermal progressive graphitization, it is shown that carbonization can go to completion in nature (ΔH ≈ 65 kcal/mole), whereas progressive graphitization is thermodynamically improbable (ΔH ≈ 260 kcal/mole).The mechanism of formation of natural graphite has thus to be determined.

Electrical resistivity (also known as specific electrical resistance, or volume resistivity) is a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current.
