Book Description
Research of the origins of life in connection with a marine environment started at the end of the seventies, when the `black smokers' in the Pacific were discovered and the Red Sea deep hydrothermal brines were found to be a fruitful environment for abiotic synthesis of life precursors. For a while this research was categorised under the heading `chemistry', but in less than a decade the topic became fully integrated into the science of 'oceanography'. The Scientific Committee on Oceanographic Research (SCOR) initiated Working Group 91: Chemical Evolution and Origin of Life in Marine Hydrothermal Systems'. This volume contains the final report of this working group.

Book Description
This book demonstrates the direct link between petroleum, the derivative of organic materials, and ore bodies. The studies reported here highlight the common factors between hydrocarbons and mineral concentrations, such as heat sources, migration routes and likely traps. It emphasizes the role that hydrothermal processes play in the genesis of both petroleum generation and ore-grade mineralization. The presence of oil residue in the form of bitumen and pyrobitumen in all sediment-hosted ore bodies throughout the geological record is a testimony to their common diagenetic history. Studies of active hydrothermal systems reported in this book describe the processes and derivatives in these environments, linking hydrocarbon generation and mineral precipitation. A comparison with residual oil in many ore bodies and mineralization occurrences in the geological record, as depicted in this book, can be explained in terms of processes in active hydrothermal systems. One of the most interesting and challenging recent discoveries, that of living nano-bacteria, is reported in this book. The `nanobes', as they have recently been dubbed, have been suggested as the link between the living and non-living matter. The resemblance of these nano-organisms to fossil forms observed in a Martian meteorite have been reported recently in the media. Likewise the similarity to nano-bacteria in Archaean sediments is highlighted in two chapters of the book.

Book Description
This volume covers the occurrence, interpretation and significance of bitumens (hydrocarbon residues) in ore deposits. Bitumens occur with a wide variety of ores, including deposits of base metals, mercury, uranium, gold and other precious metals. The papers included reflect this variety of bitumen occurrences and the potential for obtaining useful data from them. The contributions are written by acknowledged experts in this field, who cover analytical techniques and case studies using diverse petrographic and geochemical approaches which will give ore geologists and geochemists an excellent insight into the interpretation of bitumens during mineral exploration. The large number of plates in particular will help the non-specialist to make good use of the volume through the application to new deposits. This is the most comprehensive set of contributions published on a subject of growing interest; at a time when explorationists are increasingly recognising the occurrence of bitumens in ore deposits and the fact that the evolution of mineralising fluids and hydrocarbon fluids may be closely interlinked.

Book Description
Natural and Laboratory-Simulated Thermal Geochemical Processes compares a series of thermal natural geochemical events with thermally laboratory-simulated processes. The emphasis is on the geothermal events occurring in nature compared with those simulated in the laboratory, thus furnishing important information at the molecular level for such processes. The book covers the following topics: -Generation of petroleum and its thermal cracking; -Pyrolysis of oil-shales; -Formation of coal and its gasification and liquification; -Thermal liquification of biomass; -Geothermal energy; -Thermal generation of fullerenes; -Thermal formation of diamonds; -Thermal analysis of organo-clay complexes; -Geochemical conditions for life emergence.

Book Description
Gorda Ridge presents a primarily technical summary of recent advances in seafloor research related to mineral exploration of the only seafloor spreading center within the United States' Exclusive Economic Zone (EEZ). Spreading centers are known to be the locus of hydrothermal activity and to host mineral deposits of hydrothermal origin. The book includes sections on the results of mineral exploration on Gorda Ridge, the newest technologies for mineral exploration and sampling on the seafloor, and the evolving field of hydrothermal vent biology and ecology. What makes the book unique is that it is: 1) a site book, 2) a truly multidisciplinary summation of the state of the art in complementary areas of deep ocean geology and biology, and 3) a marker in the evolution of federal-state relations concerning ocean development.
