New Bouguer Gravity Maps of Venezuela: Representation and Analysis of Free-Air and Bouguer Anomalies with Emphasis on Spectral Analyses and Elastic Thickness

<table>Graph representing the natural logarithm of the radially averaged power density spectrum versus the radial wavenumber and wavelength for the Bouguer anomaly map (blue points). The straight lines present the power spectra of mass points located at a maximum estimated depth. Four sources were recognized with estimated depths (Sd) of 79, 35, 16, and 5 km.</table>
