Gravity and magnetic methods can be directly related to physical properties of rocks, i.e. the density and the susceptibility, and are very useful to field geologists and geophysicists in the mapping and identification of various rock types. They are also used for the detection of minerals with large contrast in density and susceptibility compared to country rock.
This reference volume consists of two parts: The first part describes the basic principles and methodology of the gravity and the magnetic methods of geophysical exploration with global examples. It deals with geological studies and gravity & magnetic methods; geodynamic studies (plate tectonics, crustal structures, plume tectonics); resource exploration (geological mapping, hydrocarbon, mineral and groundwater exploration); environmental studies (seismotectonics, engineering sites, climate changes, mining geophysics, volcanoes and volcanic activity, landslides, impact craters) and different modes of surveying. The second part is dedicated to the Indian Continent and deals with the application of geological data, integrated with other geophysical and geological information. It discusses geodynamics and seismotectonics with respect to the Indian Plate zone, including the Indian Ocean, Himalaya, Tibet and Archean- Proterozoic Cratons and Mobile Belts. It also presents ways for integrated exploration for hydrocarbons, minerals, groundwater and a number of environmental issues relevant in engineering and archaeology.
The accessible style of this unique work will benefit researchers, professionals, advanced students and interested readers in Geophysics, Geology, Economic Geology, Geological Engineering, Geography, Mineralogy and related disciplines.
About the Author: Dr. Dinesh Chandra Mishra obtained his Doctorate Degree from the Banaras Hindu University and worked at the Tata Institute of Fundamental Research in Mumbai. He later joined the National Geophysical Research Institute (NGRI) in Hyderabad, where he is still active as an Emeritus Scientist. He has carried out advanced geological research in many countries and guided many airborne magnetic and ground gravity surveys for exploration research in India and surrounding countries. As an expert, he has been involved with the preparation of gravity maps for geodynamics and resources exploration, integrated with other geophysical and geological information, such as satellite magnetic and gravity data. Dr. Mishra is the recipient of the National Mineral Award of the Ministry of Mines and Geology, the Business Development Award of the Council of Industrial and Scientific Research (CSIR) an the Decennial Award of the Indian Geophysical Union.
