Kerogen and extractible organic matter from immature Kimmeridge clay and Brent coal were heated at different temperatures (270-500°C) under conditions to mimic natural maturation. Aromatic fractions have been examined for their phenanthrene compound

Two types of organic matter from the North Sea have been studied, one from the Kimmeridge clay shales of the Moray Firth basin (Type II organic matter) and the other from the Brent coals of the Viking Graben (Type III). Mineral matrices were removed

Hydrogen and carbon bearing constituents depleted in 13C and D with respect to their parent material are released during coalification. The residue should therefore be continuously enriched in both isotopes with increasing maturity. Published pyrolys

Extraction of soluble organic matter from sedimentary rock by a supercritical polar fluid is feasible. In addition, if carbon dioxide is used, it has the advantage of being undetected by flame ionisation, thus allowing gas chromatography directly fol

Type III (humic) organic matter from the Mahakam delta (Indonesia) was chosen to compare artificial and natural coal series. Powdered and concentrated immature organic matter was heated in sealed gold tubes for 24 hr at temperatures ranging from 250

Petroleum is a stable colloidal sol, with a continuous transition from the smallest hydrocarbon molecules to the bulkiest micelles. Asphaltenes are the micellar fraction precipitated by n-hepatane ; in the remainder, resins—the non-hydrocarbon frac

Analytical techniques such as elemental analysis, infrared spectroscopy, ESR, dark-field electron microscopy and reflectance analysis applied to kerogens enables the geochemist to describe how they evolve at depth. Simulation of this evolution is obt

δ13 C measurements on a series of coals from the Mahakam delta (Kalimantan, Indonesia) show a progressive increase from ≈ − 29.5% at the peat-lignite transition to ≈ − 27.5% at a reflectance of R 0 ≈ 0.9. Given the very good homogeneity of
