Sediments and rocks recovered in CRP-1 coring operations contain relatively little organic matter (average 0.4% TOC) and very small amounts of solvent-soluble organic matter ( average 60 µg bitumen/g rock). The kerogen recovered from these rocks has atomic H:C ratios that range from 0.7 to 1.0 and atomic O:C ratios that range from 0.14-0.22. This range of values could be produced by mixing coal detritus with aquatic organic matter. Coal with the O:C ratios necessary to produce the kerogen present in the CRP-1 samples occurs in outcrops of the Permian Beacon Supergroup proximal to the drillsite.
Measurements were made using the technique of Hedges and Stern (1984, Limnology and Oceanography, 29: 657-663)
