Abstract:
ABSTRACT. The Euler deconvolution is a semi-automatic interpretation method of potential field data that can provide accurate estimates of horizontal position and depth of causative sources. In this work we show the application of 3D Euler Deconvolution in gravity and magnetic maps to characterize the rift structures of the Potiguar Basin (Rio Grande do Norte and Ceará States, Brazil) using the structural index as a main parameter, which represents an indicator of the geometric form of the anomalous sources. The best results were obtained with a structural index equal to zero (for residual gra

Abstract. The transform shearing between South American and African plates in the Cretaceous generated a series of sedimentary basins on both plate margins. In this study, we use gravity, aeromagnetic, and resistivity surveys to identify fault architecture and to analyse the evolution of the eastern Equatorial margin of Brazil. Our study area is the southern onshore termination of the Potiguar rift, which is an aborted NE-trending rift arm developed during the breakup of Pangea. The Potiguar rift is a Neocomian structure located in the intersection of the Equatorial and western South Atlantic

Os métodos gravimétricos e magnéticos classicamente apresentam boas respostas para o estudo do arcabouço tectônico de bacias sedimentares. Neste trabalho, foram aplicadas técnicas avançadas de processamento de dados geofísicos (redução ao polo, matched filter, gradiente horizontal total e inclinação do sinal analítico do gradiente horizontal total), com o objetivo de caracterizar a expressão geofísica das principais estruturas do Rifte Potiguar e do seu embasamento cristalino (NE do Brasil).
