Abstract

The (sin x)/x. (sin y)/y method provides a convenient way for the upward and downward continuation of potential fields. Tables of coefficients facilitating the application of this method to three dimensional problems are presentedthe method evaluated using several theoretical models. For downward continuation the method is sensitive to random actuations in the potential field dataappears limited to continuation to rather shallow depths For upward continuation the method works well and as an illustration of its use the gravity field over an area of exposed Precambrian rocks is prejected upward to different elevations; thus illustrating the anomalies which would result from basement rocks had this area been covered by up to four miles of sediments
