Summary

The data presented in this Chapter summarize the available, relevant, organic geochemical parameters for Proterozoic sediments which have, in the course of this project, been studied for their bitumen content and composition.

In Tables 19.1–19.4, “N/A” (not analyzed) indicates that an analysis was not carried out; and “NM” (not measured) indicates that a value for the parameter indicated was not determined, usually because some factor precluded its measurement. Two numbering systems are used here:

  1. (1) Samples included in the PPRG sample collection which were subjected to initial Rock–Eval screening (Chapter 16) are identified by PPRG Sample Number only. Several of these samples, together with others that were acquired late in the project, were re-analyzed at the Bureau of Mineral Resources (BMR), Canberra, Australia, and are therefore denoted by dual PPRG and BMR Sample Numbers. Data regarding the geographic and geologic origin of PPRG samples are included in Chapter 14.

  2. (2) Samples that were collected and analyzed specifically as part of BMR projects are denoted by BMR Sample Numbers only; information about the orgins of these samples is included in BMR publications and unpublished databases.
