Figure 10 A routine tool for the determination of continuity between fault blocks makes use of high-resolution GC traces. Pairs of peaks between the n-alkanes are selected and peak ratios measured. These ratios are plotted on a star diagram and if two samples from the same source are not in communication with each other it can be expected that their plots on the star diagram will not be coincident. The situation is a little less clear when two plots are coincident since this might mean the samples are in communication or it might simply be a coincidence.

In the past, most emphasis has been put on determining, statistically (e.g. cluster analysis Stolum Smalley 1992 Stolum et al. 1993)) or visually (e.g. Star diagrams Kaufman et al. 1990 Hwang Baskin 1994 Hwang et al.

The 2004 US DOE report referred to above (Werpy and Peterson, 2004) also gives "star" diagrams for the identified bio-based platform molecules to indicate how the molecules may be transformed into a variety of derivatives or secondary chemicals. The number and nature of the pathways for forming derivatives is dependent on the platform molecule used, but the authors of this valuable report have suggested the broad categorization of the derivatives into (1) those that will replace industrial petrochemicals or biochemicals and (2) tiiose tiiat...
