| Abstract: | Summary. One method to determine the depths of sources of anomalies in the Earth's gravity field is to plot log (2 n + 1) σ n ] versus n where σ n is the n th term in the amplitude spectrum of the Earth's gravitational potential. This procedure assumes that the amplitude spectrum of the anomalous density variations does not vary with n. Such an assumption may not apply to the Earth. |
