Isolated kerogens from four sites in the Middle Valley hydrothermal region of the Juan de Fuca Ridge (Ocean Drilling Project (ODP) Leg 139) were analysed by electron paramagnetic resonance (EPR) spectroscopy. Measurements of peak width, spin density and power saturation for site 857 kerogens, which increased regularly in maturity downhole, show correlation with vitrinite reflectance values from 0...
Whole rock and isolated kerogens from the Seabee, Inigok, and Ikpikpuk wells of the Alaskan North Slope have been analyzed by electron paramagnetic resonance (EPR) spectroscopy. The sample suite includes representatives of the Torok, Kingak, Lisburne, Sadlerochit and Endicott formations. Power saturation studies show a definite correlation with the downhole maturation, the extent of aromaticity...
