... The determination of the total magnetization direction is vital of importance for the inversion and interpretation of magnetic anomalies because the total magnetization direction includes the influence of strong remanent magnetization. The cross-correlation method is commonly used to estimate...

... region, we use the IDQ curve to estimate the direction of the remanent magnetization. The results show that the remanent magnetization direction, extracted from magnetic anomaly, can not only indicate the information of local geological activities, but also be used to classify the lithologies of the sub...

... In this study, the Artificial Neural Network Regression technique has been applied for inversion of gravity and magnetic anomaly datasets. Using this technique, we have tried to find the unknown parameters of the causative source, i.e., density contrast, the radius of the buried structure...

Because the magnetic survey data in this area is magnetic anomaly modulus inversion to obtain the magnetic affected by the oblique magnetization of the middle and low structure of the northeastern South China Sea. latitudes, this paper adopts...

... In oil & gas exploration, magnetic anomaly caused by reverse remanent magnetism is often ignored. With the exploration step moving to the fine stage, this problem needs to be paid great attention by the processing and interpretation researcher. In large area data processing, it is difficult...

... 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...

.... MobileMT survey data from the Grindstone Copper-Nickel-Cobalt project, New Brunswick indicate a strong correlation between conductivity highs and magnetic anomalies. 2D inversions suggest conductivity structures to be detected up to 1000–2000 m depth.

The magnetic anomalies have been analyzed at each step of both DC field magnetizing and demagnetizing and resulting magnetic characteristics of several magnetic anomalies are discussed. Based on magnetic characteristics...

... Summary Magnetic anomalies are difficult to analyze and interpret because they are not always located in the vertical direction of the perturbing bodies. Depending on the parameters of the geomagnetic field, the shape of the anomalies cannot be uniquely related to a given source...
