SIMPLIFIED MAGNETIC INTERPRETATION OF THE GEOLOGIC CONTACT AND THIN DIKE

A simple procedure has been applied to the interpretation of magnetic profiles measured perpendicular to the strike of contact or dike‐like structures. The method is very easy and rapid to apply, and is applicable to airborne or ground level data. It does not necessarily require computing facilities but may be automated if desired. As the interpretation requires only a relatively short length of traverse (usually less than 3 depth units) in close proximity to the structure, the procedure results in a high immunity to neighboring disturbances. A worked example using theoretical data shows its effectiveness.
