O arcabouço estrutural da Bacia Sedimentar do Araripe, Província Borborema, baseado em dados aeromagnetométricos

Abstract: ResumoEste trabalho apresenta uma interpretação atualizada da estruturação interna da Bacia Sedimentar do Araripe, localizada ao sul da porção setentrional da Província Borborema, por meio do processamento e da análise de dados aerogeofísicos de magnetometria pertencentes à Companhia de Pesquisa de Recursos Minerais -Serviço Geológico do Brasil. Essa bacia é reconhecida como um conjunto de meio-grábens assimétricos, fragmentados por altos de embasamento e complexos sistemas de falhas e lineamentos E-W a NE-SW,… Show more

“…A recent study based on aeromagnetic data (Camacho and Ferreira, 2017) proposed an updated structural framework for the Araripe Basin, consistent with previous works (e.g. Ponte, 1996;de Matos, 1992;Assine, 2007;de Castro and Branco, 1999), that includes up to four internal domains: Araripe-Araripina, Feitora, Crato-Juazeiro and Mauriti.…”

“…These anomalies were considered robust by the authors, because even the overlying sedimentary cover ( 1.500 m) was unable to attenuate the magnetic signal. The magnetic anomalies represent evidence of bodies with high magnetic susceptibility at depth, which may be associated with magmatic intrusions (Camacho and Ferreira, 2017).…”

“…The geological history of this intracratonic basin began about 150 Ma ago and is associated with the separation of Gondwana and the opening of the South Atlantic (Ceará State Government, 2012). The Araripe Basin stands out for its extension in area and stratigraphic amplitude, comprising four tectonostratigraphic phases called synecise, pre-rift, rift and post-rift South Atlantic (Assine, 1994;2007;Martil et al, 2007;Fambrini et al, 2011;Paula-Freitas and Borghi, 2011;Camacho and Oliveira e Sousa, 2017).…”

“…This study presents the results of 3D inverse modelling of six selected magnetic anomalies from sources located underneath and around the Araripe Basin, aiming to complement other endeavors of interpretation of the available data (e.g. Camacho, 2017). The Magnetic Vector Inversion method was selected for this work due to the presence of remanent magnetization that hinders the results of direct susceptibility inversion (Aisengart, 2013).…”
