Download or read book Himalayan Thick Skin Basement Deformation of the Ladakh Batholith Leh Ladakh Region NW India written by Michael George Petterson and published by Springer Nature. This book was released on 2023-06-01 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the first report and interpretation of the deformation, structural style, and geo-tectonic evolution of a 600km2 area of the Ladakh batholith, NW India, centred on the city of Leh, Ladakh. The Ladakh (and westerly Kohistan ) batholith comprises a large component of the Jurassic-Oligocene Kohistan-Ladakh Arc-Terrane (KLA), with magmatism spanning island arc, continental margin, and post-Himalayan collision tectonic environments. The KLA is bounded to the north by the Shyok-Northern Suture and to the south by the Indus Suture. The batholith illustrates basement thick-skin tectonic deformation and is divided/partitioned into a series of crustal blocks separated by lateral accommodation structures which allow independent movement in horizontal and vertical space. Thin skinned deformation within the adjacent sedimentary molasse Indus Suture Rocks produced large thrust stacks that predominantly moved towards the N-NE. Whilst deformation within cover sequences influences the basement structures, and helps break up the basement into crustal blocks, there is a clear distinction in deformation between the basement and cover sequences. Basement batholith deformation is more complex and heterogeneous, reflecting the variable transmission of tectonic stress within crystalline crust and the presence of a wide range of precursory inherited weaknesses and anisotropies. Models of time-space deformation are presented using data derived from field and extensive photograph / photo-mosaic image interpretation. The batholith was deformed during at least Palaeocene-Pliocene times at crustal depths that correspond to the ductile-brittle transition zone and shallower.

Download or read book Himalayan Tectonics written by P.J. Treloar and published by Geological Society of London. This book was released on 2019-10-08 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Himalaya–Karakoram–Tibet mountain belt resulted from Cenozoic collision of India and Asia and is frequently used as the type example of a continental collision orogenic belt. The last quarter of a century has seen the publication of a remarkably detailed dataset relevant to the evolution of this belt. Detailed fieldwork backed up by state-of-the-art structural analysis, geochemistry, mineral chemistry, igneous and metamorphic petrology, isotope chemistry, sedimentology and geophysics produced a wide-ranging archive of data-rich scientific papers. The rationale for this book is to provide a coherent overview of these datasets in addressing the evolution of the mountain ranges we see today. This volume comprises 21 specially invited review papers on the Himalaya, Kohistan arc, Tibet, the Karakoram and Pamir ranges. These papers span the history of Himalayan research, chronology of the collision, stratigraphy, magmatic and metamorphic processes, structural geology and tectonics, seismicity, geophysics, and the evolution of the Indian monsoon. This landmark set of papers should underpin the next 25 years of Himalayan research.

Download or read book Crustal Channel Flow Kinematics and Examples written by Soumyajit Mukherjee and published by Springer. This book was released on 2015-05-19 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the landmark paper by the Dalhousie University research group (2001, Nature) on coupled thermal–mechanical channel flow extrusion of the Higher Himalaya, there has been an intense debate on the validity and modifications of this extrusion mechanism. To understand this important ductile deformation process, one needs to grasp its fluid mechanical foundation. However, for the sake of brevity, research papers present key equations and not their detail derivations. To fill the gap, this book starts with basic fluid mechanics of channel flow and explains their ‘working principles’ by solving a number of problems. It also summarizes our current understanding of the mountain building processes related to channel flow. The book uses an easy language to help non-specialists and undergraduate students. It will be an ideal book for those geoscientists with little mathematical background who need to deal with this deformation mechanism in their research work.
Download or read book Avoidable Deaths written by Nibedita S. Ray-Bennett and published by Springer. This book was released on 2017-09-04 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses one of the most fundamental questions of the 21st century: why deaths continue to occur in natural disasters despite the tremendous advancements in disaster management science and weather forecasting systems, increased sophistication of human-built environments and ongoing economic and policy development worldwide. By presenting an interdisciplinary tool for analysing ‘systems failure’, the book provides concrete suggestions on how deaths may be reduced in resource-poor contexts. It goes beyond traditional risk and vulnerability perspectives and demonstrates that deaths in disasters are complex problems that can be solved by adopting a socio-technical perspective to improve current disaster management systems in the developing world. The book is a timely contribution, as it directly addresses Global Target One of the UN’s ‘Sendai Framework for Disaster Risk Reduction’, which has urged 185 UN Member States to reduce disaster mortality by 2030. Further, it offers a valuable resource for students, researchers, policy-makers and practitioners interested in disaster risk reduction, human rights, gender, sociology of risk, crisis and disasters, environmental science, organisation and management studies.

Download or read book Sustainable Minerals Operations in the Developing World written by Geological Society of London and published by Geological Society of London. This book was released on 2005 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sustainable development of minerals, which are non-renewable resources, is a major challenge in today's world. In this regard the true definition of 'sustainability' is a debating point in itself: can such a concept exist with respect to non-renewable resources? Perhaps the ideal sustainability model is one that minimizes negative environmental impact and maximizes benefits to society, the economy and regional/national development. Developed and near-developed economies rely for commodity supplies on developing countries where major mining operations are often a mainstay of the domestic economy. Limited environmental regulation and low wages lead to charges of exploitation. Also, large numbers of people have no alternative to living by informal, often dangerous, 'artisanal' mining. This Special Publication gives examples from developing countries from all scales of mineral extraction. The volume reviews environmental, economic, health and social problems and highlights the need to solve these before sustainability can be achieved. The better solutions require mutual understanding, through full involvement of all stakeholders, education, training and investment so that small-scale and artisanal mines can grow into well-managed operations. At larger scales, most major international mining companies have now improved their practices and are monitoring their progress, although there is no room for complacency in this rapidly changing area.
