Hydrogen-isotopic abundances of lipid biomarkers are emerging as important proxies in the
study of ancient environments and ecosystems. A decade ago, pioneering studies made use …

Kerogen, commonly defined as the insoluble macromolecular organic matter (OM)
dispersed in sedimentary rocks, is by far the most abundant form of OM on Earth. This fossil …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

The organic matter content of lake sediments contains information that helps to reconstruct
past environmental conditions, evaluate histories of climate change, and assess impacts of …

The forested swamps of the central Congo Basin store approximately 30 billion metric
tonnes of carbon in peat,. Little is known about the vulnerability of these carbon stocks. Here …

Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

The structural elucidation of small molecules using mass spectrometry plays an important
role in modern life sciences and bioanalytical approaches. This review covers different soft …

Hydrogen isotope ratios were measured on n-alkanes (n-C12 to n-C31) extracted from
recent lake surface sediments along a NS European transect to test if modern climate …

Stable hydrogen and carbon isotopic compositions of individual n-alkanes were determined
for various terrestrial plants (33 samples including 27 species) and aquatic plants (six …

Abstract The Palaeocene/Eocene thermal maximum represents a period of rapid, extreme
global warming∼ 55 million years ago, superimposed on an already warm world,,. This …
