Geomagnetic Trend Analysis In The Fayum District, Western Desert, Egypt

Abstract

The present paper contains brief results of the trend analysis of the aeromagnetic survey in the Fayum District, Western Desert, Egypt. The trend analysis was the constructed magnetic maps which included the total magnetic intensity anomalies, the residual magnetic anomalies, the second vertical derivative magnetic anomalies and the downward continuation magnetic anomalies in depth of two kms to 5 kms. The trend patterns of the anomalies and their distribution were plotted in azimuth-frequency diagrams. Results show that the trends of the anomalies are characterized by a degree of preference in orientation; specially the pattern is dominated by WNW and ENE orientations at both the Poisson's 95% and 99% significance levels.
