Figure 7.
The newly proposed ethyl-dimethyladamantane index (E-DMAI), ethyl-trimethyladamantane index (E-TMAI), and ethyl-tetramethyladamantane index (E-TeMAI) parameters versus thermal maturity for all fluids. Solid lines represent linear fits to the data for each regional group, with 95% confidence intervals of the fits in gray shading. EU = Europe; ME = Middle East; NA = North America; = adjusted coefficient of determination; SA = South America; VRE = vitrinite reflectance equivalent.
