Terpenoid biomarkers with high chemotaxonomic value, which can be used for the
identification of an angiosperm input to sedimentary organic matter are desirable for studies …

The hydrocarbon biomarker assemlage of a liptinite-rich, early Tertiary angiospermous
lignite has been characterized. The biomarker fistribution for the lignite confirms the low …

The soluble organic matter and pyrolysate from a sample suit of Triassic sediments have
been analyzed by GC-MS techniques for C-8 epimers of drimane and homodrimane. The …

Reconstructing the paleo-environmental conditions that prevailed during the deposition of
sediments provides invaluable information for paleo-ecological and evolutionary …

Weathered waxy crude oil and black asphaltite (tar) are regularly washed ashore along the
coastlines of South Australia and western Victoria. These bitumens generally strand on …

A novel S compound, 1, 4-bis (2′, 5′, 5′, 8a′-tetramethylhexahydrothiochroman)-

Abstract Sediment cores from Sagamore Lake and Woods Lake in New York State's
Adirondack Park, an area remote from industrial activities, were analyzed for polynuclear …

The natural products synthesized by organisms that were living a long time ago gave rise to
their molecular fossils. These can consist of either the original unchanged compounds or …
