Aims and scopeOrganic Geochemistry was established in response to the need for a specialized medium for the rapid publication of research in this highlyinterdisciplinary field. Currently, Organic Geochemistry serves as the only dedicated medium for the publication of research on all phases ofgeochemistry in which organic compounds play a major role. Contributions covering a wide spectrum of subjects in the geosciences broadlybased on organic chemistry (including molecular and isotopic geochemistry), and involving geology, biogeochemistry, environmentalgeochemistry, chemical oceanography and hydrology are welcome. The scope of the journal includes research involving petroleum (includingnatural gas), coal, organic matter in marine and non-marine sediments, organic-rich rocks and soils, and the role of organics in the geochemicalcycling of the elements. Sedimentological, paleontological and organic petrographic studies will also be considered for publication, providedthey are geochemically oriented. We welcome newer applications and extensions of molecular organic geochemistry which might includearchaeological chemistry, biogeochemical ecology, biomolecular paleontology and molecular stratigraphy. We also see an appropriate extensioninto the characterization and significance of petroleum reservoir inhomogeneities and the storehouse of information to be elucidated usingcompound specific isotope techniques. Papers cover the full range of research activities in organic geochemistry, and include comprehensivereview articles, technical communications, discussion/reply correspondence and short technical notes. Individual issues of OrganicGeochemistry are devoted to papers presented at symposia.
