Camacho, A.G. y Viera, Ricardo y Montesinos, F. G. y Cuellar, V. (1994) A gravimetric 3d global inversion for cavity detection. Geophysical Prospecting, 42 (2). pp. 113-130. ISSN 0016-8025
A gravimetric survey, covering a site 200 m square, was carried out in order to locate karstic cavities. After eliminating the regional trend using a polynomial fit, the residual is modelled by least-squares prediction. Correlated signals for several wavelengths are detected. The inversion of these anomalies is performed by a global 3D adjustment using spherical bodies as models. The adjustment is repeated in order to obtain a stable configuration. The results show the probable presence of a system of cavities and galleries. Data collected from boreholes and the subsequent appearance of sink-holes are consistent with the results.
