Organic Geochemistry, 2006
Abstract The present-day state as well as the history of isotope organic geochemistry is reviewed. Theoretical aspects of isotope fractionation in a system of complex organic molecules, fractionation of carbon isotopes in the biosphere, isotopes as applied to study the transformation of organic matter, geochemistry of oil and gas, evolution of the ...

Immunology and organic geochemistry
Organic Geochemistry, 1984Abstract 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).

Molecular Organic Geochemistry
1982Organic 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 ...

Organic Geochemistry The Organic Chemist’s Approach
1969My purpose in writing this chapter has been to outline the premises and methods of “molecular organic geochemistry”. This term encompasses the characterization of organic matter at the molecular level as it occurs in sediments and other natural environments.
