Deep-pass — An aeromagnetic data filter to enhance deep features in marginal basins
Autor: Darcicléa F. Santos, Luiz F. S. Braga, Valéria C. F. Barbosa, João B. C. Silva
Publikováno v: GEOPHYSICS. 77:J15-J22
An aeromagnetic data filter was tested as a tool in enhancing the magnetic responses of deep sources associated with marginal basins. Our approach consists in amplifying the responses of magnetic sources which extend through the continental slope and

Integration of High Resolution Falcon TM Gravity Gradiometry and Seismic data: an example from Northern Argentina
Autor: Marcela Lidia Fernandez, J. C. S. de Oliveira Lyrio, Alan Morgan, Luiz F. S. Braga, S.V. Yalamanchili
Publikováno v: 72nd EAGE Conference and Exhibition - Workshops and Fieldtrips.
Newly acquired airborne gravity gradient and magnetic data were used to model the tectonic framework and basement configuration beneath the Chirete concession area, onshore, northern Argentina, using the existing seismic data as constraints. The stud

Aeromagnetic delineation of the continental and oceanic crusts boundary
Autor: Darcicléa F. Santos, Luiz F. S. Braga, João B. C. Silva, Valéria C. F. Barbosa
Publikováno v: SEG Technical Program Expanded Abstracts 2005.
We present a method to delineate the boundary separating the oceanic and continent crusts using magnetic data. The method maps magnetic lineaments, which happen to occur solely in the continental crust. To this end, the magnetic signal is amplified b
