Biomarker ananlyses of the Aspen Shale(Mowry shale equivalent),Skully’s Gap,Wyoming,suggest that vital source rock properties (e.g.,kerogen hydrogen-to-carbon [H/C] ratio,Rock-Eval Hydrogen Index (HI),and maceral composition) may be indirectly,yet quantitatively,predicted from the biomarker parameters measured in oils.A strong correlation exists between the “Homohopane Index” of Aspen source rock extracts and both the H/C ratio and HI of the associated kerogen (R2=0.93 and 0.83,respectively).The percentages of C30 and C28 4-desmethyl steranes,relative to total extracted 4-desmethyl steranes,correlate with the precentage of marine-derived amorphous type Ⅱ organic matter in the kerogen (R2=0.80 and 0.73,respectively),and with kerogen H/C ratio and HI (R2=0.89 and 0.88,respectively,for C30 steranes; R2=0.89 and 0.83,respectively,for C28 steranes).The ratio of 4α-methyl-24-ethylcholestanes to 3β-methyl-24-ethylcholestanes in the extracts also correlates with kerogen H/C ratio and
