| Abstract: | The auxiliary functions, namely amplitude, phase, envelope and instantaneous frequency of Hilbert transform over gravity anomalies
of 2-D sphere, vertical fault block and horizontal circular cylinder are studied. The characteristics of these functions are
established in locating and identifying the sources. The method is illustrated with a theoretical example in each case and
supported by field data of gravity anomaly over Humble dome and spherical model of the Satak-Mansar area, Nagpur District,
India. |
