The picking of an indigenous sample was impractical so the sample was analyzed without picking. An "Adjusted TOC" value for indigenous material was calculated as follows: (F~)(TOC~)+ (F~)(TOC~) = (~)(TocT) TOCI = TOCT - (Fc)(TOCc) FI Where FI = fraction of indigenous' sample TOCI = TOC of indigenous sample FC = fraction of CAVED material TOCc = TOC of CAVED material TOCT = TOC of Total sample The data are presented inAppendix A. In like manner, adjusted values have been computed f o r the Rock-Eva1 data. These are shown in AppendixB. No adjustments were neededf o r the visual kerogen data since the red beds do not contain any kerogen of any significance. Y .A.
