A compilation of existing magnetic data clearly demonstrates the presence of extensive, NE-SW trending, linear anomalies over the central Venezuelan Basin. These long wavelength, small amplitude anomalies are truncated in the east by a series of N-S linear anomalies over the Aves Ridge, and in the south by E-W trending anomalies over the Aruba Basin, Curacao Ridge, and Los Roques Basin. In the southeastern corner of the basin, there is a magnetic quiet zone similar to that observed in the North Atlantic and Pacific Oceans.
Analysis of the NE-SW anomalies reveals an axis of symmetry which crosses the basin from...
