Thirty-five different samples from three different sulfur cycles were examined in this stratigraphically oriented study of the Shell 22x-1 well (U.S.G.S. C177 core) in the Piceance Basin, Colorado. Carbon isotopic compositions of constituents of Green River bitumens indicate mixing of three main components: products of primary photoautotrophs and their immediate consumers (? ?30? vs PDB), products of methanotrophic bacteria (? ?85?), and products of unknown bacteria (? ?40?). For individual compounds synthesized by primary producers, ?-values ranged from ?28 to ?32?. 13C contents of individual primary products (?-carotene, steranes, acyclic isoprenoids, tricyclic triterpenoids) were not closely correlated, suggesting...
