Advances in Organic Geochemistry 1964 contains papers presented at the Second International Congress on Organic Geochemistry at Rueil-Malmaison, France on September 28-30, 1964. This collection discusses developments made in the field of organic-chemistry and the incorporation of organic matter with clay minerals. To understand the process involved in such association of materials, the text explains the overall reaction between the clay particles and all the organic and inorganic substances in the test solution. The study gives the trace element assemblages found in the Mansfield Marine Band as an example. Another study discusses the occurrence of isoprenoid alkanes in a Precambrian sediment where alkanes and porphyrin pigments, which remain stable for a long time in many geological conditions, can act as biological markers. The paper notes the Marker Bed of the Precambrian Nonesuch Shale Formation in Michigan. The book also presents more research such as those involving the Black Shales of the South-east Sicilian Triassic Basin and the Cretaceous Black Shales of the Cyrenaica Basin. The text then explains the use of electron spin resonance in studying concentrations of free radicals where the results of different measurements made on a Colorado coal are shown on a table. One paper addresses a study of the relative abundance of stable carbon isotopes as pointers to the evolution and genesis of petroleum. This collection will prove valuable for analytical and organic chemists, chemical engineers, geologists, and students of organic chemistry or geology.

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.

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.

This volume presents the most significant papers given during the 13th International Meeting in Organic Geochemistry. The intention of the publication is to provide the scholars of this science with its state-of-the-art and recent papers not only in academic research but above all in practical applications. Several papers attest to an increased use of organic geochemistry not only in the oil industry, during all phases of petroleum exploration, but also in the other research areas of coal origin and structure, metallogeny, sedimentology, molecular palaeontology, biochemistry and pollution.

For many years, the subject matter encompassed by the title of this book was largely limited to those who were interested in the two most economically important organic materials found buried in the Earth, namely, coal and petroleum. The point of view of any discussions which might occur, either in scientific meetings or in books that have been written, was, therefore, dominated largely by these interests. A great change has occurred in the last decade. This change had as its prime mover our growing knowledge of the molecular architecture of biological systems which, in turn, gave rise to a more legitimate asking of the question: "How did life come to be on the surface of the Earth?" A second motivation arose when the possibilities for the exploration of planets other than the Earth-the moon, Mars, and other parts of the solar system-became a reality. Thus the question of the possible existence of life elsewhere than on Earth conceivably could be answered.

This book reviews the present status of organic geochemistry and its application to Petroleum Exploration. It is intended to be as practical as possible with all aspects of geochemistry illustrated by a great number of examples taken from case histories from all over the world which show that geochemistry must be used in the framework of a good geological/geophysical background. This book is written for: petroleum geologists and geophysicists; managers who should integrate the impact of geochemistry in exploration decision-making; specialized geochemists who need an accurate panorama of other aspects of geochemistry; university professors and students in petroleum geology.

Developments in Economic Geology, 15: Geochemical Exploration 1980 focuses on practices, processes, methodologies, and principles involved in geochemical exploration. The selection first takes a look at the simultaneous determination of sulfide, polysulfides, and thiosulfate as an aid to ore exploration; hydrogeochemical exploration for uranium ore deposits; and mercury and mercury compounds in surface air, soil gas, soils, and rocks. Discussions focus on the methods of mercury analysis, calibration, sensitivity and computations, exploration, titration of hydrogen sulfide, polysulfides, thiosulfate and sulfite, and leaching of a sulfide deposit by percolating water. The book then examines meteorological noise in crustal gas emission and relevance to geochemical exploration; a mercury vapor survey in an area of thick transported overburden in Shanghai, China; and mechanisms of ore formation and primary dispersion at the Dexing porphyry copper deposit in Jiangxi and their implications to geochemical exploration. The publication explores the organic matter of a gulf coast well studied by a thermal analysis; selective extraction procedures applied to geochemical prospecting in an area contaminated by old mine workings; and application of radionuclide energy-dispersive X-ray fluorescence analysis in geochemical prospecting. The selection is a vital source of data for researchers interested in geochemical exploration.
