Abundances and Isotopic Compositions of Carbon and Sulfur Species in Whole Rock and Kerogen Samples

Abstract

In this Chapter are presented compilations of data regarding the abundance and isotopic composition of carbon and sulfur obtained for PPRG samples during the course of this project (Tables 17.1, 17.2, 17.5, 17.6), compilations of results of such analyses previously reported for Precambrian samples (Tables 17.3, 17.7, 17.9), and summary tables listing all available Precambrian results for the abundance and isotopic composition of carbon in whole rock samples (Table 17.4), for the abundance and isotopic composition of sulfur in sulfides and sulfates (Table 17.8), and for the elemental and carbon isotopic composition of kerogens (Table 17.10). Analytical procedures used to obtain the results here reported for PPRG samples are described in Chapters 15 and 16. Comparable compilations regarding the composition of organic matter extractable from Precambrian samples are presented in Chapter 19, the analytical procedures for which are discussed in Chapter 18. In each of the ten tables presented in this Chapter, data are grouped by geologic unit, ordered geochronologically from youngest to oldest; within each unit, data for PPRG samples are ordered by PPRG Sample Number. Explanation of symbols Reference Code . In Tables 17.3, 17.4, 17.7, 17.8, and 17.10, sources of previously published data are indicated by a ten-character reference code in which the first four characters are the first four letters in the surname of the first author of the publication; the following two characters are the last two numbers of the year of publication; and the final four characters encode the page number of the initial page of the publication.
