Insights into the morphology of the Serra da Cangalha impact structure from geophysical modeling
(WILEY-BLACKWELLHOBOKEN, 2012)
Forward modeling is commonly applied to gravity field data of impact structures to determine the main gravity anomaly sources. In this context, we have developed 2.5-D gravity models of the Serra da Cangalha impact structure ...
Integration of geoelectric and geochemical data in the evaluation of natural attenuation in a diesel contaminated site in Sao Manuel (Brazil)
(Inst Geophysics Unam, 2017-07-01)
Geophysics is a very relevant investigation tool in conjunction with chemical analysis, during the diagnosis and monitoring of contamination in the geological environment. This paper presents the results of DCdefine ...
