... Magnetic surveys involve measuring the response of the total magnetization in rocks. Total magnetization is the vector sum of induced and remanent magnetization. It is common to overlook remanence and assume induced magnetization is dominant during interpretation and modeling. This case study...

... In this paper, we develop a method of jointly inverting airborne gravity gradiometry (AGG) and total magnetic intensity (TMI) data in the presence of remanent magnetization. The goal is to obtain structurally similar 3D density and magnetization models. In addition, in the areas with remanent...

... ABSTRACT We propose a technique to reconstruct the magnetic anomaly from a dike in a way that the influence of the induced magnetization, remanent magnetization, and geological dip are completely removed, resulting in a new totally symmetric anomaly that could avoid the need of reduction...

..., allowing the definition of the horizontal projection of the source. We perform tests in synthetic data simulating a main geomagnetic field (main field) with vertical incidence and at low latitudes. The sources that give rise to the simulated anomalies have both induced and strong remanent magnetizations...

... ABSTRACT The effect of remanence has long been recognized as an obstacle for the interpretation and modeling of magnetic data. In this paper, we propose a Cooperative Magnetic Inversion (CMI) algorithm for the 3-D inversion of magnetic data affected by remanent magnetization. The CMI algorithm...

... ABSTRACT The convertional approaches for apparent magnetization mapping usually neglect effects of remanence, resulting in large geologic deviation or occurrence of negative magnetization when the subsurface contains strong remanent magnetization. We present a space-domain inversion approach...

... ABSTRACT The remanent magnetization may contain information about the formation process, mineralogy, and possibly geological history of different units. The magnitude of magnetization helps define the spatial configuration and structure of magnetic causative bodies, while the magnetization...

... on the assumption that there is no remanent magnetization, and the inversion is run for magnetic susceptibility only. However, this approach ignores the situation where the direction of magnetization of the rocks is different from the direction of the induced magnetic field. This situation happens in a case...

..., Colorado School of Mines Summary The presence of remanent magnetization hinders the recovery of the regional or global lithospheric magnetic structures using satellite observed magnetic data. To overcome this difficulty, we utilize the amplitude of the anomalous magnetic field, which is weakly dependent...

... synthetic and field examples. Introduction Magnetization vector inversion (MVI) is becoming an important tool in the quantitative interpretation of magnetic data affected by strong remanent magnetization. Many authors have approached this problem in the context of parametric inversion (e.g., Silva...

..., in strong magnetic field environments, it is sometimes difficult to accurately interpret for magnetic sources due to the complex role played by remanent magnetization and the self-demagnetization effect. The inducing magnetic field in Brazil is about three times weaker compared with regions of high magnetic...
