Download or read book Holocene Sedimentary Record from the Sunda Shelf Off Peninsular Malaysia Insights from Elemental Isotopic and Bulk Sediment Magnetic Susceptibility Analyses written by Haley Hindes and published by . This book was released on 2016 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post-Last Glacial Maximum (since ca. 20,000 cal yr BP) sediments of the Sunda Shelf (southern South China Sea) are generally thin, with the exception of incised valleys where thicker accumulations tend to occur. These valleys provide a sedimentary record that preserves Holocene environmental changes. In the summer of 2014, two ca. 2 m gravity cores were collected on the Sunda Shelf in ca. 60 m of water ca. 52 km from the mouth of the Terengganu River off northeast peninsular Malaysia. Both cores were sampled in 1 cm contiguous intervals and analyzed for magnetic susceptibility of bulk sediment (BMS), elemental composition (X-ray fluorescence, XRF), and oxygen and carbon stable isotopes on the planktonic foraminifer Globigerinoides ruber. The chronology of the cores, based upon eight AMS radiocarbon age estimates on the benthic foraminifer Cavarotalia annectens, covers most of the Holocene. According to previous work, the Holocene evolution of the Sunda Shelf was largely controlled by the transgression of the South China Sea (SCS) shoreline following the Last Glacial Maximum. Several sea-level curves suggest sea level in the area had reached ca. -60 m by the start of the Holocene (ca. 11,700 cal yr BP). According to this study, at ca. 10,000 cal yr BP, the Sunda Shelf off northeast Peninsular Malaysia was already covered by ca. 30 m of water, evident by the presence of benthic foraminifera and marine mud throughout both cores. The study area transitioned from a shallow, muddy, nearshore environment to an open shelf environment (ca. 60 m water depth and at least 50 km from shore) during the 10,000 - 6,400 cal yr BP time interval. This is indicated by steadily decreasing Al, Ti, and Fe concentrations up-core, steadily increasing Ca concentrations up-core, and the first occurrence of planktonic foraminifera at ca. 7,000 cal yr BP. Between 6,000 - 4,000 cal yr BP, previous studies indicate the mid-Holocene sea-level highstand was reached. This study suggests the presence of a possible diastem at ca. 6,400 cal yr BP in TER14-GC5 based on an abrupt change in BMS and XRF data, which could be related to the maximum flooding surface. Core TER14-GC7 reveals the same shift in elemental and BMS trends at ca. 6,400 cal yr BP, but the transition is more gradual. The up-core profile of XRF and BMS trends reveal a shift from higher BMS values to lower BMS values, steady Ca concentrations, and higher but fluctuating presence of planktonic foraminifera after ca. 6,400 cal yr BP. The changes recorded by the two cores during the ca. 6,400 - present time interval are interpreted as the late transgressive systems tract transitioning to the highstand systems tract (HST). The HST is typically characterized by fine-grained sediments, with abundant foraminifera, that were deposited as the rate of sea-level rise slowed. However, the changes recorded during this time interval could also be explained by a decrease in precipitation in the area, possibly due to a decrease in monsoon intensity. Further investigation is needed to properly understand the time interval from ca. 6,400 cal yr BP - present in order to determine whether trends in the data sets are due to climate or other environmental change.
Download or read book Geology of the China Seas written by Pinxian Wang and published by Elsevier. This book was released on 2014-06-07 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geology of the China Seas represents the first English-language synthesis of the available research into the geology of the South and East China Seas. Among the marginal basins worldwide, these areas have been the focus of extensive research activities in the last three decades, and are now among the global hot spots in hydrocarbon explorations and scientific investigations. The region is experiencing rapid economic development with the offshore petroleum industry providing approximately one third of the domestic hydrocarbon production for mainland China. Gas hydrates have been successfully recovered from the China Seas for the first time. Over the years, many volumes on the geology of the China Seas have been published in Chinese. Although an increasing number of papers in English have appeared recently, the majority deal with local or regional paleo-environment and sedimentology, and are scattered in different journals. This book brings together this rich data in one resource, particularly that generated by Chinese marine geologists and petroleum geologists, and provides the very first synthesis of the geology off China. - The first systematic summary of the geology of the China Seas - Includes comprehensive coverage of the South China Sea and the East China Sea, including the Yellow Sea and Bohai Gulf - Reviews hundreds of Chinese publications on marine and petroleum geology not currently accessible to the international community
Download or read book Submerged Landscapes of the European Continental Shelf written by Nicholas C. Flemming and published by John Wiley & Sons. This book was released on 2017-08-07 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quaternary Paleoenvironments examines the drowned landscapes exposed as extensive and attractive territory for prehistoric human settlement during the Ice Ages of the Pleistocene, when sea levels dropped to 120m-135m below their current levels. This volume provides an overview of the geological, geomorphological, climatic and sea-level history of the European continental shelf as a whole, as well as a series of detailed regional reviews for each of the major sea basins. The nature and variable attractions of the landscapes and resources available for human exploitation are examined, as are the conditions under which archaeological sites and landscape features are likely to have been preserved, destroyed or buried by sediment during sea-level rise. The authors also discuss the extent to which we can predict where to look for drowned landscapes with the greatest chance of success, with frequent reference to examples of preserved prehistoric sites in different submerged environments. Quaternary Paleoenvironments will be of interest to archaeologists, geologists, marine scientists, palaeoanthropologists, cultural heritage managers, geographers, and all those with an interest in the drowned landscapes of the continental shelf.
Download or read book The South China Sea written by Pinxian Wang and published by Springer Science & Business Media. This book was released on 2009-05-27 with total page 506 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pinxian Wang and Qianyu Li The South China Sea (SCS) (Fig. 1. 1) offers a special attraction for Earth scientists world-wide because of its location and its well-preserved hemipelagic sediments. As the largest one of the marginal seas separating Asia from the Paci?c, the largest continent from the largest ocean, the SCS functions as a focal point in land-sea int- actions of the Earth system. Climatically, the SCS is located between the Western Paci?c Warm Pool, the centre of global heating at the sea level, and the Tibetan Plateau, the centre of heating at an altitude of 5,000m. Geomorphologically, the SCS lies to the east of the highest peak on earth, Zhumulangma or Everest in the Himalayas (8,848m elevation) and to the west of the deepest trench in the ocean, Philippine Trench (10,497m water depth) (Wang P. 2004). Biogeographically, the SCS belongs to the so-called “East Indies Triangle” where modern marine and terrestrial biodiversity reaches a global maximum (Briggs 1999). Among the major marginal sea basins from the west Paci?c, the SCS presents some of the best conditions for accumulating complete paleoclimatic records in its hemipelagic deposits. These records are favorable for high-resolution pa- oceanographic studies because of high sedimentation rates and good carbonate preservation. It may not be merely a coincidence that two cores from the southern 14 SCS were among the ?rst several cores in the world ocean used by AMS C dating for high-resolution stratigraphy (Andree et al. 1986; Broecker et al. 1988).

Download or read book Volcanoes written by John P. Lockwood and published by John Wiley & Sons. This book was released on 2013-04-26 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanoes are essential elements in the delicate global balance of elemental forces that govern both the dynamic evolution of the Earth and the nature of Life itself. Without volcanic activity, life as we know it would not exist on our planet. Although beautiful to behold, volcanoes are also potentially destructive, and understanding their nature is critical to prevent major loss of life in the future. Richly illustrated with over 300 original color photographs and diagrams the book is written in an informal manner, with minimum use of jargon, and relies heavily on first-person, eye-witness accounts of eruptive activity at both "red" (effusive) and "grey" (explosive) volcanoes to illustrate the full spectrum of volcanic processes and their products. Decades of teaching in university classrooms and fieldwork on active volcanoes throughout the world have provided the authors with unique experiences that they have distilled into a highly readable textbook of lasting value. Questions for Thought, Study, and Discussion, Suggestions for Further Reading, and a comprehensive list of source references make this work a major resource for further study of volcanology. Volcanoes maintains three core foci: Global perspectives explain volcanoes in terms of their tectonic positions on Earth and their roles in earth history Environmental perspectives describe the essential role of volcanism in the moderation of terrestrial climate and atmosphere Humanitarian perspectives discuss the major influences of volcanoes on human societies. This latter is especially important as resource scarcities and environmental issues loom over our world, and as increasing numbers of people are threatened by volcanic hazards Readership Volcanologists, advanced undergraduate, and graduate students in earth science and related degree courses, and volcano enthusiasts worldwide.

Download or read book Climate Change in Prehistory written by William James Burroughs and published by Cambridge University Press. This book was released on 2005-06-13 with total page 370 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did humankind deal with the extreme challenges of the last Ice Age? How have the relatively benign post-Ice Age conditions affected the evolution and spread of humanity across the globe? By setting our genetic history in the context of climate change during prehistory, the origin of many features of our modern world are identified and presented in this illuminating book. It reviews the aspects of our physiology and intellectual development that have been influenced by climatic factors, and how features of our lives - diet, language and the domestication of animals - are also the product of the climate in which we evolved. In short: climate change in prehistory has in many ways made us what we are today. Climate Change in Prehistory weaves together studies of the climate with anthropological, archaeological and historical studies, and will fascinate all those interested in the effects of climate on human development and history.
Download or read book Reservoir Characterization written by Larry Lake and published by Elsevier. This book was released on 2012-12-02 with total page 680 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reservoir Characterization is a collection of papers presented at the Reservoir Characterization Technical Conference, held at the Westin Hotel-Galleria in Dallas on April 29-May 1, 1985. Conference held April 29-May 1, 1985, at the Westin Hotel—Galleria in Dallas. The conference was sponsored by the National Institute for Petroleum and Energy Research, Bartlesville, Oklahoma. Reservoir characterization is a process for quantitatively assigning reservoir properties, recognizing geologic information and uncertainties in spatial variability. This book contains 19 chapters, and begins with the geological characterization of sandstone reservoir, followed by the geological prediction of shale distribution within the Prudhoe Bay field. The subsequent chapters are devoted to determination of reservoir properties, such as porosity, mineral occurrence, and permeability variation estimation. The discussion then shifts to the utility of a Bayesian-type formalism to delineate qualitative ""soft"" information and expert interpretation of reservoir description data. This topic is followed by papers concerning reservoir simulation, parameter assignment, and method of calculation of wetting phase relative permeability. This text also deals with the role of discontinuous vertical flow barriers in reservoir engineering. The last chapters focus on the effect of reservoir heterogeneity on oil reservoir. Petroleum engineers, scientists, and researchers will find this book of great value.
