Organic Geochemistry Of Biomarkers

Annual Review of Earth and Planetary Sciences, 1987
The classic organic chemical studies by the German chemist Alfred Treibs on the structures of tetrapyrrole-type compounds in crude oils led him to propose a biological origin for crude oils (Treibs 1934, 1 936). Treibs based his proposal on structural determinations, made by classical chemical methods, of porphyrins (I) in the oils and their structural

Immunology and organic geochemistry

Organic Geochemistry, 1984
Abstract Two “conventional” antibody preparations directedn against fractions of soluble macromolecules from shells of the recent bivalve Ensis ensis were allowed to react with shell fragments of a large variety of invertebrates, mainly molluscs. Use was made of a special adaptation of the Enzyme-Linked ImmunoSorbent Assay (ELISA).

Origins of organic geochemistry

Organic Geochemistry, 2008
When organic geochemistry actually began as a recognized geoscience is a matter of definition and perspective. Constraints on its beginning are placed by the historical development of its parent disciplines, geology and organic chemistry. These disciplines originated independently and developed in parallel, starting in the latter half of the 18th ...

Molecular Organic Geochemistry

1982
Organic geochemistry can be characterized as a field of science which studies the “fate” of organic compounds in sediments. In its earlier days research efforts were limited — from sheer lack of other possibilities — to the determination of bulk characteristics as for instance contents of organic carbon, nitrogen, hydrogen and percentage of organic ...
