Computer Technology for Modeling the Sources of Magnetic Anomalies in the Layers of the Earth’s Crust

Abstract

AbstractThis paper illustrates new methods to investigate the anomalous magnetic field of the lithosphere and to module sources of anomalies in different layers of the earth's crust. The interpretation consists of three stages: separation of anomalies from sources in different layers of the earth's crust, the transformation of the data to the pole and solution of the inverse problem of finding the surface of the sources. New computer technology was used with an application of parallel computing on multiprocessor computer systems. The results are presented for the Western Ural region, covering the eastern part of the old East-European platform and the Ural orogen. The models of the sources of magnetic anomalies in the granite layer and the surface of the basaltic layer are constructed for magnetization 3 and 4 A/m. Results of the study allowed us the determination of the position of the deep faults in the upper crust of the Western Ural and their connection with the deep belt of magnetized ultrabasic-basic complexes projecting above the basalt layer of the earth's crust.KeywordsMagnetic anomalyEarth’s crustModeling
