| Abstract: | Summary. A technique for rapid calculation of the vertical gravitational attraction of three-dimensional axially symmetric bodies using the one-dimensional Fast Fourier Transform (FFT) is presented and discussed. The calculation is rapid, efficient and accurate, and requires only a simple linear array to describe the body shape. This method is most useful for calculation of the gravity effect of long-wavelength bodies such as oceanic seamounts or sedimentary basins and for the gravity effect of annular bodies such as up-warped sedimentary strata around a salt diapir. |
