Sediments from the world's ocean floors and other water body basins hold a wealth of information about organic life as we know it. Organic Matter: Productivity, Accumulation, and Preservation in Recent and Ancient Sediments addresses focusing on the production, accumulation, and preservation of organic matter in marine and lacustrine sediments. Contributors to this important monograph cover a range of geologic ages from recent times back to the Permian Era, as well as temperature and organic matter types. This resource book will be of interest and benefit to petroleum explorationists and researchers, as well as oceanographers, marine and environmental scientists, sedimentologists, geochemists and paleontologists.

Sedimentation rate could become a new exploration tool for evaluating the source rock potential of sedimentary basins in frontier regions. Petroleum source rocks are defined on the basis of total organic carbon by weight percent. An analysis of Deep Sea Drilling Project (DSDP) cores indicates that there exists quantitative relationships between sedimentation rate and total organic carbon content in fine grained ancient marine sediments of Jurassic, Cretaceous and Cenezoic age. These relationships are independent of geographic setting, geologic age, and differential compaction, but are highly dependent upon lithology. For any given sedimentation rate, the total organic carbon content increases from calcareous to siliceous to black shale sediments. For each of these lithologies, the total organic carbon content increases with sedimentation rate due to reduced aerobic microbial degradation at higher burial rates. Above a critical sedimentation rate, the total organic carbon content may decrease with increasing sedimentation rate due to a clastic dilution effect. Aerobic microbial degradation, however, continues to be less efficient at higher burial rates. Therefore, even though the total organic carbon content may decrease, the quality of the organic matter preserved and the oil generation and oil migration potential of the sediment may continue to increase with increasing sedimentation rate. Similar relationships have also been established between total organic carbon and grain accumulation rate, and total organic carbon accumulation rate and grain accumulation rate. These relationships support both reduced aerobic microbial degradation and the clastic dilution effect. In the latter case, the lithologic control is less pronounced, and the relationship can be used to determine total organic carbon content even when the lithology is not known. The results of this study have important implications for petroleum exploration in frontier regions. Sedimentation rate and grain accumulation rate could be determined from seismic isopach and velocity data. When the lithology is not known, such as prior to exploration drilling, grain accumulation rates could be used to estimate the total organic carbon content, and the oil generation and oil migration potential of a sedimentary basin. Once the lithology is known, the source rock potential of the basin can be more accurately predicted. Future work should be directed toward testing the application of sedimentation rate and grain accumulation rate in the petroleum exploration of frontier regions.

The flux, preservation, and accumulation of organic carbon in marine systems are controlled by various mechanisms including primary p- duction of the surface water, supply of terrigenous organic matter from the surrounding continents, biogeochemical processes in the water column and at the seafloor, and sedimentation rate. For the world's oceans, phytoplankton productivity is by far the largest organic carbon 9 source, estimated to be about 30 to 50 Gt (10 tonnes) per year (Berger et al. 1989; Hedges and Keil 1995). By comparison, rivers contribute -1 about 0. 15 to 0. 23 Gt y of particulate organi.

This open access book discusses biogeochemical processes relevant to carbon and aims to provide readers, graduate students and researchers, with insight into the functioning of marine ecosystems. A carbon centric approach has been adopted, but other elements are included where relevant or needed. The book focuses on concepts and quantitative understanding of primary production, organic matter mineralization and sediment biogeochemistry. The impact of biogeochemical processes on inorganic carbon dynamics and organic matter transformation are also discussed.

Depositional models for organic-carbon-rich sediments have been the subjects of both great interest and great controversy for many years. These sediments serve as the ultimate source of virtually all oil and gas. They also represent the interface between biological and geological processes and provide critical evidence for the state of the atmosphere and oceans. Yet despite their importance and decades of research, the origin of these sediments remains the source of vigorous disagreement. The twelve papers in this volume represent the cutting edge of research in this topic. They explore the origin of organic-carbon-rich sediments through a variety of techniques, including sedimentology, geochemistry, paleontology and computer modeling. All papers take multidisciplinary approaches to the topic, and together, they demonstrate the complex interconnected processes that trigger the deposition of organic carbon. This book will appeal to geoscientists in many disciplines, including explorers for petroleum who need models for source rock deposition, organic and inorganic geochemists who study processes in water and sediment, sedimentologists who interpret ancient deposition environments, and climatologists and oceanographers who reconstruct the behavior of the ancient atmosphere and oceans.
