Abstract

The gravity data of the Usangu sedimentary basin in southern west Tanzania is analyzed<br>using Hartley transform. The Hartley transform is found to accomplish spectral analysis that<br>could be achieved using the Fourier transform.<br>The spectral depths determined from the radial spectrum reveal an average depth of the<br>regional component of about 5 km, intermediate depth of 2.0 km and shallow depths of 1 km.<br>Enhancement of the gravity data by calculating second vertical derivatives and downward<br>continued maps give results that enhance shallow structures. The upward continued and the<br>matched filtered maps also give maps that enhance regional anomalies under the expense of<br>shallow structures.<br>The filtering of the gravity data has revealed that the sediments are overlying basement of<br>different lithologies.
