| Abstract: | The objectives of this investigation are a) to develop an analytical technique for evaluating two- and three-dimensional interpretations of crustal structure in a quantitative manner by use of digital computers, b) to utilize gravity and seismic measurements to analyze the crustal structure underlying Campeche Bank, Mexico using the technique developed herein, and c) to infer, from the approach used in this research, the orogenic history of the region. A contour map of observed gravity anomaly values was constructed and profiles were drawn on this map to serve as simulated observed traverses. Various mathematical models of the crust underlying Campeche Bank were assumed for these profiles and analyzed first by the two-dimensional, line-integral method, then by a three-dimensional, numerical quadrative method. Computer programs developed for this technique gave the contributions of each layer to the total computed gravitation attraction along each profile. ... |
