;
Green River oil shale kerogen was prepared by HCl/HF treatment and extensive Soxhlet extraction (C/sub 6/H/sub 6//CH/sub 3/OH at azeotropic ratio) before and after mineral removal. The kerogen was subjected to mild stepwise oxidation using Na/sub 2/Cr/sub 2/O/sub 7/ in glacial CH/sub 3/COOH. The oxidation products as their methyl esters were analyzed by capillary gas chromatography and combined gas chromatography-mass spectrometry. A dominant series of 17..beta..(H)-hopane derivatives (C/sub 30/-C/sub 33/) were identified. The presence of these compounds suggests a significant algal contribution during diagenesis and points toward a mild thermal history for this Green River oil shale sample.
