Abstract:
The Excello is a Pennsylvanian (Desmoinesian) cyclothemic black shale, whose extent reaches from Illinois to Oklahoma passing through Kansas and Missouri. Though not a traditional source rock, the Excello is well defined stratigraphically and lithologically which makes it a perfect candidate to test the relationship between variations in uranium and total organic carbon with respect to depositional environments. The purpose of this study is to test the hypothesis that high concentrations of uranium correlate with high organic carbon concentrations only when phosphate is absent in the rock. Further refinement of our understanding of the relationship between U and organic carbon, serves to strengthen the use of well log interpretation as a proxy for mudrock characterization, as well as basin wide correlations of mudrocks in general.
