Gravity Field Seismicity And Tectonics Of The Indian Peninsula And The Himalayas

Recent developments in Science and Technology have removed the boundaries betwe~n the so-called 'fundamental' and 'applied' fields of research. This has been particularly evident in the rapidly expanding geophysical sciences with their far reaching applications. Fundamental geophysical studies of surface, subsurface and crustal structures where gravity investigations play an important role, are of immediate potential importance in defining major structural features or geological units which may control or influence the development of metallogenic provinces, petroleum potential areas or coal fields. Gravity studies in India have a long history and tradition. The earliest gravity measurements were made with two brass pendulums loaned by the Royal Society of England, when Basevi and Heaviside established 30 gravity pendulum stations between Cape Comorin and Ladakh during 1865 to 1873. Over the subsequent years, large areas of the country have been systematically covered through gravimeters and a number of regional and detailed studies have been undertaken by various agencies like Survey of India, Geological Survey of India (GSI), Oil and Natural Gas Commission (ONGC), National Geophysical Research Institute (NGRI) and a number of universities. Assistance was provided by late Prof. G. P. Woollard and his former students Muckenfuss, Bonini, Shankaranarayan and Murali Manghnani, who have connected India to the international gravity net work. Gravity studies carried out by the Survey of India have been of great value in geodetic studies.

This volume presents the results on contemporary geodynamic model, crustal stress field, active faults, folds and volcanoes. It discusses the tectonophysical environments of earthquake generation and the methodology of earthquake prediction.

Proceedings of the Seventh International Conference on Basement Tectonics, held in Kingston, Ontario, Canada, August 1987

This edited book presents a novel collection of field-based empirical studies on the Quaternary geomorphology of the Lower Ganga Basin. The book covers a wide range of topics discussing various geomorphological facets of the Lower Ganga and its subsidiary rivers focussing on laterites, palaeoenvironment and palaeogeomorphology, palaeo-coastal landforms, neo-tectonism, tidal-fluvial dynamics, extra-channel geomorphology and channel-pattern adjustment among others. Various methodologies were applied ranging from historical records and religious texts to state-of-the-art remote sensing and GIS techniques. The book appeals to all scientists and post-graduate students of geomorphology and related areas who want to acquire detailed knowledge of the geology and geomorphology of the Lower Ganga Basin or are in search of new methodologies for studying the feedback mechanisms between forms and processes.

Tectonic Setting and Gondwana Basin Architecture in the Indian Shield, Volume Four, is the newest book in the Problems and Solutions in Structural Geology and Tectonics series from Elsevier, and is a synthesized monograph on the tectonic settings of Gondwana basins of India. It is a unique book on a topic of national and international interest, especially given the economic importance of the region (coal reserves). The book is authored and edited by very experienced theoretical experts and explores and reconstructs unified stratigraphic research of the region, including the relative role of tension and lateral movement in basin formation. Basin formation is the driving force behind formation and break-up of supercontinents and the time frame of supercontinent cycles. Provides the latest data on the tectonic settings of Gondwana basins of India Explores the unified stratigraphic research of the region Authored and edited by experienced theoretical experts

The book is a thoughtful discussion with scientists studying convergent plate boundaries such as the well-known, active India-Eurasia collision zone. It provides a comprehensive collection of petrographic images of ophiolitic rocks exhumed from oceanic lithosphere and mantle at the India-Asia plate boundary. Ophiolite is exposed in the northwestern Himalayas, eastern Indian plate margin and Andaman-Nicobar Islands. At the eastern margin, it occurs in a narrow strip comprising mantle peridotite tectonite, cummulate peridotite-gabbro-plagiogranite-anorthosite, mafic dyke, volcanics and oceanic sediments. Low temperature/high pressure rocks including blueschists and eclogites were extensively studied recently. Ophiolite derived sediments and podiform chromites will also be discussed to provide complete details. Supplemental maps, geological sections, field sketches and photographs will explain the structure, stratigraphy, ore mineralization, and metamorphic history.

The ihsan Ketin NATO Advanced Study Institute on the Tectonic Evolution of the Tethyan Region was conceived in 1982 in Veszprem, Hungary, when three of the organizers (B. C. B. , L. H. R. and A. M. C. 9. ) had come together for a meeting on the tectonics of the Pannonian basin. All three of us had experience in the Tethyan belt and all three of us had been for some time deploring the lack of communication among workers of this immense orogenic belt. Much new work had been completed in such previously little-known areas as Turkey, Iran, Afghanistan, the People's Republic of China, the entire Himalayan region, as well as new work in the European parts of the chain. Also, ironically, parts of the belt had just been closed to field work for political reasons, so it seemed as if the time was right to sit back and consider what had been done so far. Because the Istanbul group had had an interest in the whole of the Tethyan belt and because that ancient city was more centrally locElted with excellent opportunities to see both Palaeo- and Neo-Tethyan rocks in a weekend excursion, we thought that Istanbul was a natural place for such a meeting, not mentioning its own considerable attractions for the would-be contributors. A happy coincidence was that Prof.
