PAES GONZALEZ, SHAYANE (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Geofísica, 2023-10-25)
We developed a new ambiguity analysis method for appraisal the remanent-magnetization direction and the Koenigsberger ratio (Q) of a uniformly magnetized source. Our method is grounded on a new formulation of the unit ...

DA SILVA PIAUILINO, LARISSA (Observatorio NacionalDivisão de Programas de Pós-Graduação - DIPPGBrasilONPrograma de Pós-Graduação em Geofísica, 2023-12-15)
We propose two fast equivalent-layer techniques for processing large gravity gradient and magnetic datasets. Based on the equivalent-layer principle, we assume that potential-field data produced by arbitrary geological ...
