Comparação de métodos de estimativa de profundidades de fontes magnéticas utilizando dados aeromagnéticos da província mineral de Carajás, Pará

Abstract: ABSTRACT. With the goal of providing an effective analysis for assessment and interpretation of depth to magnetic sources, depth estimates were yielded from high density, aeromagnetic data collected over the Serra Leste region (Carajás Mineral Province, Pará State, Brazil), by three distinct methods: (i) Euler Deconvolution; (ii) Analytic Signal; and (iii) Local Wavenumber. According to the results obtained by these three methods, most of the magnetic sources in the study area are located above 100 m depth. St… Show more

“…Also, the κ parameter can be related to other soil secondary minerals, like ferrihydrite and hematite (Valaee et al, 2016). The great potential of this technique is related to geological studies (Shenggao, 2000;Correia et al, 2010), soil texture, and organic carbon studies (Camargo et al, 2014;Jiménez et al, 2017), soil surveys (Grimley et al, 2004), and pedogenesis and pedogeomorphological processes (Viana et al, 2006;Sarmast et al, 2017;.…”

“…O estado do Pará possui a segunda maior província mineral do mundo no que se refere aos depósitos de ferro, de ouro, de manganês e de cobre. A principal região está localizada na Serra dos Carajás, sudeste do estado, que se situa na margem sudeste do Cráton Amazônico e faz parte da Província Amazônia Central (Correia et al, 2010). Dois blocos tectônicos arqueanos compreendem a Província Mineral de Carajás: o mais velho, ao sul do rio Maria, os terrenos Granito-Greenstone, ao norte, o Cinturão de Cisalhamento Itacaiúnas (Galarza & Macambira, 2002), que incorpora uma das sequências vulcanossedimentares arqueanas melhor preservadas do mundo, a Bacia de Carajás.…”
