This book was released on 2015-01-05 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The geophysical investigation of the subsurface structures of parts of Benue Trough and Bornu Basin, northeast Nigeria, using aeromagnetic data was studied. The area is bounded by latitude 9.5N to 12.0N and longitude 9.5E to 12.0E. The residual data were subjected to structural analysis using Centre for Exploration Targeting grid plug-ins, 2D subsurface modelling and depth analyses using spectral depth and SPI. The magnetic trends has a dominant trend in northwest-southeast. The results of CET showed that the two basins Bornu and Benue had similar structural relationship with more structural activities in Bornu Basin, the Basement Complex region and the volcanic areas. The maximum sedimentary thickness obtained with spectral analysis was 3.72km. The result of the SPI has its maximum thickness of about 5.0km. The result of 2D modelling showed that the sedimentary thicknesses ranged from 0.0km to a maximum of 4.6km. The maximum thicknesses were found around central areas to northeast. The maximum sedimentary thicknesses obtained is adequate for hosting of hydrocarbons. The end results of these methods showed that Benue Trough was separated from the Bornu Basin at about latitude 11.0N

This book was released on 2022-04-21 with total page 643 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited book is based on the best papers accepted for presentation during the 2nd Springer Conference of the Arabian Journal of Geosciences (CAJG-2), Tunisia, in 2019. It is of interest to all researchers practicing geophysics/seismology, structural, and petroleum geology. With four sections spanning a large spectrum of geological and geophysical topics with particular reference to Middle East, Mediterranean region, and Africa, this book presents a series of research methods that are nowadays in use for measuring, quantifying, and analyzing several geological domains. It starts with a subsection dedicated to the latest research studies on seismic hazard and risk assessment in Africa presented during the 2019 IGCP-659 meeting organized alongside the CAJG-2. And, it includes new research studies on earthquake geodesy, seismotectonics, archeoseismology and active faulting, well logging methods, geodesy and exploration/theoretical geophysics, petroleum geochemistry, petroleum engineering, structural geology, basement architecture and potential data, tectonics and geodynamics, and thermicity, petroleum, and other georesources. The edited book gives insights into the fundamental questions that address the genesis and evolution of our planet, and this is based on data collection and experimental investigations under physical constitutive laws. These multidisciplinary approaches combined with the geodynamics of tectonic provinces and investigations of potential zones of natural resources (petroleum reservoirs) provide the basis for a more sustainability in the economic development.

This book was released on 2014-10-10 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author applied 3D analytic signal technique to aeromagnetic data over the Zaria area of Northwest Nigeria. The analytic signal transformation of potential data has vital application in lithologic mapping by distinguishing intrusive rocks from the surrounding rocks. The result was used to map the boundary of the granitic rocks and structural discontinuities and also to delineate the Batholith Complex in the area. Researchers and students of earth sciences including applied geophysicists and geologists interested in regional mapping and study of batholiths, and or in the application of modern Geophysical edge detection techniques in crustal studies and the delineation of large rock bodies such as Batholiths will find this work useful.

This book was released on 2014-04-24 with total page 1083 pages. Available in PDF, EPUB and Kindle. Book excerpt: Providing a balance between principles and practice, this state-of-the-art overview of geophysical methods takes readers from the basic physical phenomena, through the acquisition and processing of data, to the creation of geological models of the subsurface and data interpretation to find hidden mineral deposits. Detailed descriptions of all the commonly used geophysical methods are given, including gravity, magnetic, radiometric, electrical, electromagnetic and seismic methods. Each technique is described in a consistent way and without complex mathematics. Emphasising extraction of maximum geological information from geophysical data, the book also explains petrophysics, data modelling and common interpretation pitfalls. Packed with full-colour figures, also available online, the text is supported by selected examples from around the world, including all the major deposit types. Designed for advanced undergraduate and graduate courses in minerals geoscience, this is also a valuable reference for professionals in the mining industry wishing to make greater use of geophysical methods.

This book was released on 2015-08-25 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been several works on magnetic basement depth determination using aeromagnetic data. However majority of these works has been done using the old data of 1970's with a flight line spacing of 2km, average terrain clearance of 150m, and a nominal tie line spacing of 20km and in map form which is of lower resolution. This work re-evaluated parts of Middle Benue trough Nigeria employing a more frequent automatic source depth technique in spectral analysis; and an old empirical depth method (maximum and half slope techniques) using the new high-resolution airborne Aeromagnetic surveys(HRAM)flown in Nigeria in 2009 at 500m line spacing and 80m terrain clearance and of higher resolution and in digital form. The area studied is part of middle Benue trough Nigeria of map N0: (251,252,271 and 272) with every other details shown in this work. Magnetic basement depth was obtained using both methods which compared favourably despite the huge differences between each method. The theories behind each method was well presented and the theoretical expressions and calculation easy to follow and understand.
Download or read book Potential Theory in Gravity and Magnetic Applications written by Richard J. Blakely and published by Cambridge University Press. This book was released on 1996-09-13 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text bridges the gap between the classic texts on potential theory and modern books on applied geophysics. It opens with an introduction to potential theory, emphasising those aspects particularly important to earth scientists, such as Laplace's equation, Newtonian potential, magnetic and electrostatic fields, and conduction of heat. The theory is then applied to the interpretation of gravity and magnetic anomalies, drawing on examples from modern geophysical literature. Topics explored include regional and global fields, forward modeling, inverse methods, depth-to-source estimation, ideal bodies, analytical continuation, and spectral analysis. The book includes numerous exercises and a variety of computer subroutines written in FORTRAN. Graduate students and researchers in geophysics will find this book essential.
