摘要：

We have derived and calibrated an interpretive model for estimating porphyrin concentration in bitumen and kerogen from spectral reflectance data in the visible and near-ultraviolet region of the spectrum. Preliminary results obtained using the model are consistent with concentrations determined from the bitumen extract and suggest that 40 to 60% of the total porphyrin concentration remains in the kerogen after extraction of bitumen from thermally immature samples. The reflectance technique will contribute to porphyrin and kerogen studies and can be applied at its present level of development to several areas of geologic and paleo-oceanographic research.
