Abstract
The preparation of total magnetic field anomaly map scale 1:1000000 , has been based on the magnetic field map of the same scale, prepared by French company C.G.G. in 1974 [1]. This map has offered with a contour interval 20 gamma on a base map of scale 1: 1000000, which also contained the basic topographic features of rivers, lakes and main valleys, in addition to the cities and the main illustration sites .
The preparation of the total magnetic field map of Iraq in this scale is for the purpose of industrials and strategic site selection projects throughout the country, through the creation of magnetic base information, and using geographic information system GIS, and take advantage of this information in this scale to study the topography and the nature of crystalline base rocks and its impact on the surface. In addition to the detection of the regional dynamic image, which represents the basis of the detailed seismotectonic situation. As well as the benefit in a broader and more comprehensive when planning the detailed geologic studies for site selection of any industrial or stratigic project at any point in Iraq.
The general view of the patterns in the magnetic anomalies map showing the rules of en–echelon systems extending in three distinct trends consistent with the direction of many large rivers, streams and valleys patterns.
