Abstract:

The equivalent source concept is used in the wavenumber domain to correct distortions in potential‐field data caused by topographic relief. The equivalent source distribution on a horizontal surface is determined iteratively through forward calculation of the anomaly on the topographic surface. Convergence of the solution is stable and rapid. The accuracy of the Fourier‐based approach is demonstrated by two synthetic examples. For the gravity example, the rms error between the corrected anomaly and the desired anomaly is 0.01 mGal, which is less than 0.5 percent of the maximum synthetic anomal

Abstract:

Skeletonization is a syntactic pattern‐recognition method that is applied to gridded data to produce an automatic line drawing, with an associated event catalog. Previous implementations of skeletonization have been tailored for seismic data. Here, we modify that technique to render it more suitable for other types of gridded data, with particular emphasis on aeromagnetic maps. A modification from previous schemes is the use of a two‐pass approach, to reduce the effects of an otherwise problematic directional bias that discriminates against events oriented parallel to columns of the grid.

Abstract:

The composite aeromagnetic anomaly map of Australia, like similar maps of other continent‐size regions, contains spurious trends, warps, and base‐level shifts. These arise from the arbitrary nature of aeromagnetic data processing methods and edge matching of disparate surveys. Corrections have been applied to the Australian map based on long aeromagnetic control traverses flown around the country in January and February 1990. The control traverses were timed to coincide with a continent‐wide magnetometer array study, thus enabling accurate corrections to be made for transient (diurnal) variati

Abstract:

We present a novel approach for the combination of aeromagnetic and satellite data applying an equivalent dipole layer and spherical harmonic (SH) expansion of the dipoles. The method involves two steps: (1) inversion for the magnetic parameters of the equivalent dipole layer and (2) conversion of the magnetic parameters into SH coefficients. With this approach, SH analysis can be used for a regional study area, and, for example, the long-wavelength range of aeromagnetic data can be replaced with satellite data. We test our approach on the third, fourth, and fifth editions of the Magnetic Anom

Band-limited magnetic anomalies over the Canadian Shield, for wavelengths of ~500–2200 km, derived from the magnetometer satellite (MAGSAT) data correlate peak for peak with the corresponding anomalies derived from the aeromagnetic data. This suggests that the anomalies detected by MAGSAT are physically meaningful. A new potential field satellite, Geopotential Research Mission (GRM), has been proposed to fly at about 160 km altitude. The magnetic anomaly map that can be derived from the GRM data is expected to have a resolution about an order of magnitude higher than the one derived from MAGSA

This work shows the Bouguer and aeromagnetic anomaly maps of the Iberian Chain (NE Spain) and surroundings in relation to its main geological and structural units. In general, both gravity and aeromagnetic anomalies are aligned following the same trends in both maps highlighting the major role played by the structural configuration of the Iberian Chain on their origin. In detail most anomalies do not coincide, pointing to different potential field sources to account for them. Further studies would be needed to decipher the origin of most magnetic anomalies observed in the Iberian Chain.

Abstract:

In the early 1920s, magnetic anomalies were thought to be caused by topographic relief at the base of the sedimentary section. The drilling of the Hobbs anomaly on the Central Basin Platform in West Texas was successful, but the anomaly, primarily intrabasement in origin, could not quantitatively be related to the structure that was found. Moreover the drilling of similar anomalies in the general area proved unsuccessful as far as oil and gas were concerned, so the method acquired a bad reputation rather quickly (Heiland, 1940).

Abstract:

Magnetic data sets over deep ocean areas may contain clues to the existence of craters formed by the impact of an extraterrestrial body with the Earth’s ocean crust. To aid in the magnetic exploration of the ocean crust for oceanic impact craters, basic but effective computations from an impact model are studied from an aeromagnetic point of view. The main assumption of the analysis is that a sufficiently large impact can excavate large volumes of magnetized basalt, vaporize basalt, and raise basalt to temperatures above the Curie temperature (approximately 500°C) to alter the preimpact magnet

Aeromagnetic surveys play an important role in many fields, for example, archaeology, anti-submarine warfare, and geophysical exploration.

Conventional aeromagnetic compensation methods consider that the geomagnetic gradient is approximately zero after bandpass filtering, bringing about the inaccuracy of compensation coefficients.

Abstract:

The Midcontinent Rift System (MRS) is a 1.1 Ga sequence of voluminous basaltic eruptions and multiple intrusions followed by widespread sedimentation that extends across the Midcontinent and northern Great Lakes region of North America. Previous workers have commonly used seismic-reflection data (Great Lakes International Multidisciplinary Program on Crustal Evolution [GLIMPCE] line A) to demonstrate that the northern rift margin in central Lake Superior developed as a normal growth fault that was structurally inverted to a reverse fault during a compressional event after rifting had ended.

Abstract:

The aeromagnetic survey is a common remote sensing tool for detecting iron deposits. The local wavenumber of a magnetic anomaly is used to interpret the edges or positions of the sources, and can involve first- or second-order local wavenumbers. In this paper, we derived a linear equation between the second-order local wavenumber and the source location; therefore, we propose a constraint of first and second-order local wavenumbers. Tests on synthetic data show that the source parameters, computed using a combination of equations that involved different-order local wavenumbers, are closer to t

Abstract:

The studied area is located in the east of Sana’a, Yemen, between latitudes 1700000 - 1720000 N and longitudes 430000 - 450000 E. Geological and aeromagnetic maps of the region (Sheet 13G, scaled at 1:250,000) are among the data used. By analyzing the available aeromagnetic data, the current work seeks to comprehend the regional subsurface structures and their contributions to surface geological formations. A number of analysis methods, such as regional/ residual separation, spectral analysis and Euler deconvolution have been used to critically interpret the aeromagnetic map. According to the

Abstract:

The growing need for an industrialized world, especially in Africa, cannot be feasible without adequate mineral resources. Thus, the search for more mineral deposits will continue to be necessary. An integrated approach involving geological mapping and a high-resolution geophysical (aeromagnetic) investigation was conducted to assess the manganese mineralization in parts of the Oban Massif, southeast Nigeria. The aeromagnetic data were processed using regional-residual anomaly separation techniques, first vertical derivative (1VD), analytical signals, source parameters imaging (SPI), and Euler

<strong>Abstract</strong> The geological structures of Obokun Local Government Area, Osun State, Nigeria, were delineated using aeromagnetic data. These structures control the topography, size, spacing, orientation, and shape of the hills, ridges, valleys, and drainage system of the area. The research area is located within the Ilesha Schist Belt, in the southwestern part of Nigeria's Basement Complex, with low-to-medium-grade metasediments, closely related to subordinate mafic bodies and frequently surrounded by migmatite-gneiss suite rocks. The investigation involved the abstraction of the a

Abstract:

AbstractGravity and aeromagnetic data sets provide systematic coverage over the whole of the Welsh Basin. Physical property information shows considerable overlap in densities within the Lower Palaeozoic and Precambrian formations, with relatively few units of the exposed succession being strongly magnetic. While the geophysical anomalies cannot be interpreted unambiguously in terms of these sources, the data can still be used to test different geological models and to indicate the range of possible solutions. The major fault zones are seen to influence the anomaly patterns in a variety of way
