An Introduction to Organic Geochemistry explores the fate of organic matter of all types,
biogenic and man-made, in the Earth System. investigates the variety of pathways and …

PAHs are primarily emitted by anthropogenic activities, and although some natural and
secondary sources of these contaminants are discussed, the focus of this chapter is the …

To study the largest source of river sediment to the Arctic Ocean, we have collected
suspended particulates from the Mackenzie River in all seasons and sediments from the …

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 …

The distribution of triterpanes in sediments and crude oils is commonly used for oil/oil and
oil/source rock correlation in petroleum geochemistry while isomer ratios of such …

Triterpenoids and their derivatives are ubiquitous in sediment samples. Land plants are
major sources of nonhopanoid triterpenoids; these terpenoids comprise a vast number of …

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

Peats in a sediment core from Ruoergai bog, which has a cold and moist plateau climate
with major source input from herbaceous plants, have been studied by GC–MS in order to …

Polycyclic aromatic hydrocarbons (PAHs) of environmental concern have been described
with regards to their origins. The anthropogenic PAHs from primarily combustion are the …

Higher plant biomarkers occur in various compound classes with an array of isomers that
are challenging to separate and identify. Traditional one-dimensional (1D) gas …
