APPENDIX
*NOTE:
These samples were mixtures of caved red mudstones and indigenous
material. 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.
