Carbon, nitrogen and sulphur of sediment core CRP-1 (Table 1)

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.
