A novel C24 acyclic isoprenoid, 2, 6, 15, 19-tetramethylicosane (TME), has been
unambiguously identified, using a synthesised standard, in the saturated hydrocarbon …

Upper Cretaceous amber from the Raritan Formation (Sayerville, New Jersey) has been
investigated by Pyrolysis-GC-MS and Pyrolysis-GC-matrix isolation FTIR-MS. Results …

The oleananes, as markers for the angiosperms, provide valuable source and age
information when present in an oil. Nevertheless, they are not quantitatively related to the …

We conducted molecular biomarker and compound-specific carbon isotope analyses of off-
line pyrolyzates from lacustrine samples recovered by ONEZ-1 well (the Kissenda …

A series of novel methylated phytanylbenzenes (phytanylbenzene, 1-methyl-3-
phytanylbenzene, 1, 4-dimethyl-2-phytanylbenzene, 1, 2-dimethyl-4-phytanylbenzene and …

The solvent extractable organic compounds of two fossil conifer species from the Eocene
Buchanan Lake Formation, Axel Heiberg Island, Canada, were compared to the compound …

A novel series of tricyclic ring-C monoaromatic terpanes and a minor group of tricyclic
diaromatic terpanes were characterized in Tasmanian tasmanite. The monoaromatic series …

Esters of phytol or related isoprenoid acids and fatty acid esters of pentacyclic triterpenoid
alcohols and sterols have been isolated from lacustrine sediments varying in age from …

This study examines the molecular geochemistry of depositional environments with a
predominance of terrigenous higher-plant organic matter. All analyses have been performed …

We compared structural biopolymers from morphologically well-preserved Metasequoia
tissues from three Tertiary deposits and detected a continuum of biochemical preservation …
