Download or read book Non-volcanic Rifting of Continental Margins written by Geological Society of London. This book was released on 2001. Available in PDF, EPUB and Kindle. Book excerpt: Non-continental margins lack thick lavas that are generated as continental crust thins immediately prior to the onset of seafloor spreading. They may form up to 30 per cent of passive margins around the world. This volume contains papers examining an active margin, fossil margins that border present day oceans, and remnants of margins exposed today in the Alps. The papers present evidence across a range of scales, from individual mineral grains, through borelide cores and outcrop, to whole margins at the crustal scale.

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).

Book Synopsis Rheology and Deformation of the Lithosphere at Continental Margins by : Garry D. Karner

Download or read book Rheology and Deformation of the Lithosphere at Continental Margins written by Garry D. Karner. This book was released on 2004. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, investigations of the rheology and deformation of the lithosphere (the rigid or mechanically strong outer layer of the Earth, which contains the crust and the uppermost part of the mantle) have taken place at one scale in the laboratory and at an entirely different scale in the field. Laboratory experiments are generally restricted to centimeter-sized samples and day- or year-length times, while geological processes occur over tens to hundreds of kilometers and millions of years. The application of laboratory results to geological systems necessitates extensive extrapolation in both temporal and spatial scales, as well as a detailed understanding of the dominant physical mechanisms. The development of an understanding of large-scale processes requires an integrated approach. This book explores the current cutting-edge interdisciplinary research in lithospheric rheology and provides a broad summary of the rheology and deformation of the continental lithosphere in both extensional and compressional settings. Individual chapters explore contemporary research resulting from laboratory, observational, and theoretical experiments.

Book Synopsis Passive Margins by : K.R. McClay

Download or read book Passive Margins written by K.R. McClay. This book was released on 2020-07-01. Available in PDF, EPUB and Kindle. Book excerpt: This volume has evolved from papers written in memory of Professor David Roberts. They summarize the key findings of recent research on passive margins, from tectonics, bathymetry, stratigraphy and sedimentation, structural evolution and magmatism. Papers include analyses of the central and southern Atlantic margins of South America and Africa, papers on magmatism and extension in the NE Brazilian margin and on the Cote de Ivoire margin, rift architectures of the NW Red Sea margin, tectonics of the eastern Mediterranean margin, salt tectonics of passive margins of the Gulf of Mexico and Brazil, and papers on the NW Shelf margin of Australia. The volume provides readers with new insights into the complexities of passive margin systems that are in reality, not so passive.
