Pristane/phytane ratios are a robust indicator of depositional environment.
- class="label">•
XRD data also are a good indicator of source rock organofacies.
- class="label">•
Carbonate is the strongest organofacies differentiator within CCQ ternary plots.

Source rocks have appreciable vertical and lateral compositional variability.

Multiple lines of evidence are always recommended to differentiate organofacies.
