Cool Water Carbonates

During the past decade, work on cool-water carbonates has expanded to become a mainstream research area. Studies on modern and Quaternary deposits will continue to be important; however, there is increasing momentum towards unravelling sediment processes, biota-sediment interactions and diagenetic products in Cenozoic and older cool-water carbonates. Many contributions in this book document Cenozoic and Quaternary carbonates from landlocked (microtidal) water-bodies. These carbonates display important differences in biota and fabric distributions when compared with world ocean examples. Consequently, the scientific community is now better placed to reinterpret pre-Tertiary carbonates where there is a suspicion that they have developed under microtidal conditions. Some papers in the book provide new approaches to interpreting environmental change within macrotidal regimes and others lay firm foundations for future cool-water carbonate diagenetic research. The aim of the book is to illustrate recent international contributions to cool-water carbonates research, with an emphasis on Neogene and Recent case studies. Contributions are divided into three sections: microtidal carbonates from the Mediterranean realm; macrotidal examples from New Zealand, Australia and Mexico; and early diagenetic fabrics.

The biological influence over the origin, distribution, composition, texture, and mineralogy of carbonate sediments is stressed. Environmental factors such as light, temperature, and water depth directly affect these biological processes. Abiotic carbonate precipitation is discussed. Three carbonate factories are identified: shallow water tropical; deep water mud mound; cool-water factory developed in high and low latitudes. Basic attributes of each factory are developed. The rimmed shelf and ramp facies models of the tropical factory are detailed with the Belize shelf and Middle East Abu Dhabi as examples. The facies tract of the mud mound factory is detailed and the Devonian Canning Basin used as an example. The role of sea-level changes and carbonate sedimentation in platform development is discussed. High sea-level carbonate sediment shedding combined with lowstand sediment starvation is opposite to what is seen in regions of siliciclastic sedimentation. The dominance and importance of the Dunham rock classification is stressed. Finally, lacustrine carbonates are discussed using the African rift lakes as modern examples and developing a simple model of continental rift lake carbonate sedimentation emphasizing potential source rock and reservoir facies. The Brazil Cretaceous subsalt play of the south Atlantic rift and the potential of its African counterpart are discussed.

This textbook provides an overview of the origin and preservation of carbonate sedimentary rocks. The focus is on limestones and dolostones and the sediments from which they are derived. The approach is general and universal and draws heavily on fundamental discoveries, arresting interpretations, and keystone syntheses that have been developed over the last five decades. The book is designed as a teaching tool for upper level undergraduate classes, a fundamental reference for graduate and research students, and a scholarly source of information for practicing professionals whose expertise lies outside this specialty. The approach is rigorous, with every chapter being designed as a separate lecture on a specific topic that is encased within a larger scheme. The text is profusely illustrated with all colour diagrams and images of rocks, subsurface cores, thin sections, modern sediments, and underwater seascapes.

The Cenozoic carbonate systems of Australasia are the product of a diverse assortment of depositional and post-depositional processes, reflecting the interplay of eustasy, tectonics (both plate and local scale), climate, and evolutionary trends that influenced their initiation and development. These systems, which comprise both land-attached and isolated platforms, were initiated in a wide variety of tectonic settings (including rift, passive margin, and arc-related) and under warm and cool-water conditions where, locally, siliciclastic input affected their development. The lithofacies, biofacies, growth morphology, diagenesis, and hydrocarbon reservoir potential of these systems are products of these varying influences. The studies reported in this volume range from syntheses of tectonic and depositional factors influencing carbonate deposition and controls on reservoir formation and petroleum system development, to local studies from the South China Sea, Indonesia, Kalimantan, Malaysia, the Marion Plateau, the Philippines, Western Australia, and New Caledonia that incorporate outcrop and subsurface data, including 3-D seismic imaging of carbonate platforms and facies, to understand the interplay of factors affecting the development of these systems under widely differing circumstances. This volume will be of importance to geoscientists interested in the variability of Cenozoic carbonate systems and the factors that controlled their formation, and to those wanting to understand the range of potential hydrocarbon reservoirs discovered in these carbonates and the events that led to favorable reservoir and trap development.

Few fields of research in the earth sciences have produced as much data and litera ture as the study of carbonate sediments and rocks. The past 25 years in particular, have seen a significant increase in studies concerning modern marine and fresh water carbonates. With the present worldwide interest in oceanographic research, marine carbonates have received the bulk of the attention, particularly with respect to shallow-water sediments. However, in terms of the variety of environ ments, compositions and modes of formation, non-marine carbonates probably encompass a wider spectrum than do marine types. Our purpose is to present a two-volume treatise on carbonate sediments and rocks, both marine and non-marine. We have confined ourselves to the discussion of modern (Holocene) environments, sediments and components, assuming that the compilation of these data will not only be relevant to those working with modern carbonates but will also serve as a necessary reference source for those interested in ancient analogs. The first volume, by MILLIMAN, deals almost exclu sively with marine environments, while the second volume, by MULLER and FORST NER, will concentrate on the non-marine carbonates.
