Van Krevelen diagram.[1]
A plot of atomic oxygen/carbon (O/C) versus atomic hydrogen/carbon (H/C) originally used to classify coals and predict compositional evolution during thermal maturation, but adapted to classify kerogen types I, II, III, and IV. More common is the pseudo-Van Krevelen diagram, where Rock-Eval pyrolysis oxygen index ([OI] mg HC/g TOC) is plotted versus hydrogen index ([HI] mg HC/g TOC).[2]
