A graphical method of determining the possible presence of a remanent component of magnetization in two dimensional igneous masses within the basement is described. It is required to assume that the same source produces well defined gravity and magnetic anomalies. The method involves taking the ratios of distance between peaks of maximum values of gravity and magnetic for various angles of field inclinations. Ratio of maximum positive and maximum negative values for various angles of field inclinations are also used. These ratios are plotted against field inclinations. Examples of anomalies are taken from the western desert area of the stable shelf in Iraq.
