Organic petrology of epi-impsonite at Page, Oklahoma, U.S.A.

January 1, 1991

Impsonite (asphaltic pyrobitumen) occurs as fracture-filling veins cutting massive sandstone in the frontal Ouachita Mountains near Page, Oklahoma. The Page impsonite formed from low-temperature alteration of crude oil. Mean maximum bitumen reflectance in oil immersion (Rmax) of seven samples is 1.41-1.96%. Mean apparent bireflectance of these samples is 0.15-0.54%. The Page deposit classifies at the upper end of epi-impsonite in the generic classification for solid bitumen, based on physical, chemical, and optical characteristics, and as post-oil with unlimited migration in the genetic classification for solid bitumen. ?? 1991.
