Advances in Organic Geochemistry is a collection of proceedings presented at the Third International Congress on Organic Geochemistry held in London on September 26-28, 1966. The papers explore advances in organic geochemistry and cover a wide range of topics, from carbon isotope variations in marine sediments to hydrogen isotopic fractionation of water passing through trees. Correlation problems among crude oils and the origin of trace metal enrichment in bituminous shales are also discussed. Comprised of 34 chapters, this volume begins by presenting the results of a carbon isotope study on methane from German coal deposits, followed by an analysis of the significance of carbon isotope variations in marine sediments. Subsequent chapters deal with the geochemical aspects of the occurrence of porphyrins in mineral oils and rocks in West Venezuela; pentacyclic triterpanes from petroleum; geochemical prospecting for petroleum; and the geochemical significance of pore fluid in shales. The nitrogenous constituents of deep-sea sediments are also considered, along with transformations of normal fatty acids in sediments and thermal alteration of organic matter in sediments. This book will be of interest to organic chemists and geochemists.

Advances in Organic Geochemistry documents the proceedings of the First International Meeting of the European Branch of the Organic Geochemistry Group held in Milan on September 10-12, 1962. This compilation discusses research and review problems relating to the geochemistry of organic materials in the earth's crust, such as petroleum and coal, as well as less highly concentrated, but more widespread, organic matter present in various rocks, soils, and waters. Other topics covered include duplex origins of petroleum; chemical study of coal macerals; mineralized micro-structures in carbonaceous meteorites; primary investigation of the oleiferous dolerite of Dyvika; and organic residues in Jurassic oolitic limestones. Geochemical aspects of the microbial modification of carbon compounds; trace metal analysis of oils and asphalts by neutron activation techniques; and application of ultraviolet spectroscopy to the examination of dissolved organic substances in water are also deliberated in this text. This publication is beneficial to students and individuals conducting work on organic geochemistry.

Advances in Organic Geochemistry 1968, Volume 31 contains the proceedings of the 4th International Meeting on Organic Geochemistry, held in Amsterdam, Netherlands, on September 16-18, 1968. The papers explore advances in several fields of organic geochemistry, including organic compounds found in sediments, geochemistry of coal and petroleum, and organic geochemistry of the oceans. This book is comprised of 39 chapters and begins with a discussion on the distribution of hydrocarbons and fatty acids in living organisms and in sediments, paying particular attention to biological markers and the carbon skeleton concept. The reader is methodically introduced to the mechanisms of formation of petroleum from sediment organic matter; dissolved organic matter in the oceans; the fatty acid content of tasmanites; and identification of steranes and triterpanes from a geological source using capillary gas liquid chromatography and mass spectrometry. The chemistry of coal and crude oil metamorphism is also considered, along with the racemization of amino acids on silicates. The final chapter focuses on carbon polytypism in meteorites. This volume will be useful to organic chemists, geochemists, and all those interested in the field of organic geochemistry.

Petroleum geochemistry has turned out to be more than another step in the direction to quantify geology and geosciences in general. Petroleum geochemistry as it is today may very well be the triggering event that brings the other branches of geosciences like sedimentology, stratigraphy, structural geology, geophysics and others to a fruitful synthesis as evidenced by integrated basin studies.

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 biogeochemical transformations that carbon compounds can experience over a range of time scales and in different environments scope widened to provide a broad and up-to-date background - structured to accommodate readers with varied scientific backgrounds essential terminology is defined fully and boxes are used to explain concepts introduced from other disciplines further study aided by the incorporation of carefully selected literature references It investigates the variety of pathways and biogeochemical transformations that carbon compounds can experience over a range of time scales and in different environments.
