Bouguer Gravity Regional and Residual Separation by K. Mallick,A. Vasanthi,K.K. Sharma Pdf

The process of regional-residual separation in potential field is age-old. Broadly, there are two techniques for regional-residual resolution, viz., graphical and analytical. Both the techniques have their own respective shortcomings. In this book, the authors have described the technique based on finite element method in which only eight (or twelve) nodal observed gravity values are used for the regional computation, thereby eliminating the possible contamination of anomalous fields and also the technique does not assume an explicit model and physical properties like density of rocks etc. in the regional computation. The book discusses the advantages of this technique viz., it is not site-specific; the computation is independent of any prior assumptions as to the form and depth of shallow or deeper structures; it can handle data distributed at random or on a regular grid on the map space; and the neighbouring surveys join smoothly. The book focuses on application of this new technique which has been demonstrated in different fields, such as hydrocarbon, minerals and groundwater, structural studies, earthquake and engineering studies and impact structures.

Gravity, Geoid and Earth Observation by Stelios P. Mertikas Pdf

These Proceedings include the written version of papers presented at the IAG International Symposium on "Gravity, Geoid and Earth Observation 2008". The Symposium was held in Chania, Crete, Greece, 23-27 June 2008 and organized by the Laboratory of Geodesy and Geomatics Engineering, Technical University of Crete, Greece. The meeting was arranged by the International Association of Geodesy and in particular by the IAG Commission 2: Gravity Field. The symposium aimed at bringing together geodesists and geophysicists working in the general areas of gravity, geoid, geodynamics and Earth observation. Besides covering the traditional research areas, special attention was paid to the use of geodetic methods for: Earth observation, environmental monitoring, Global Geodetic Observing System (GGOS), Earth Gravity Models (e.g., EGM08), geodynamics studies, dedicated gravity satellite missions (i.e., GOCE), airborne gravity surveys, Geodesy and geodynamics in polar regions, and the integration of geodetic and geophysical information.

Applications of Gravity Anomalies in Geophysics by Henglei Zhang,Meixia Geng,Victor Sacek,Filippo Greco,Penfei Liu Pdf

Knowledge of the density of the subsurface of a planet is crucial in determining its interior structure, and one can estimate the average bulk crustal density directly using the admittance between topography and gravity, which has been successfully used for the Moon and is being extended to Mars. The interpretation of gravity data is commonly done by computation of a gravity anomaly (GA) by correcting the raw data for a number of factors that impact the gravity field. Depending on the target science, different types of GA can be computed, the interpretation of which have been widely employed in geophysics to explore the interior of the Earth and other planets, through applications in airborne gravity, near-surface geophysics, regional geophysics, and planetary geophysics. Yet how to extract a great variety of information from GAs for applications in geophysics entails further investigation. Over the decades, remarkable progress has been made to extract information from GAs identified from data. For instance, a series of 3D inversion algorithms facilitates the extraction of the subsurface density distribution. With the improved processing based on dense gravity observations that yield high precision and high resolution GAs, more detailed geological information can be unveiled. When using the admittance between topography and gravity to estimate the crustal density, it is essential to identify what kinds of GAs to be used, such as Bouguer gravity or free-air gravity. Also, what appropriate approaches to scrutinize the applications of GAs in various case studies (e.g., calculating the geoid and estimating the elastic thickness) need to be decoded.

Gravity Field, Seismicity and Tectonics of the Indian Peninsula and the Himalayas by R.K. Verma Pdf

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.
