The performance and final results, however, are affected by many factors, including the acquisition system, acquisition parameters, quality control procedures, and the ruggedness of the terrain. We studied repeat surveys using 3D full tensor gradiometry and Falcon AGG systems under identical survey-design parameters over the Baú Mine Site, Quadrilátero Ferrífero, State of Minas Gerais, Brazil. We also evaluated the planning and quality control procedures adopted for acquisition through these systems. We also studied the results from the two systems in terms of signal-to-noise ratio, power spectral analysis, and correlation with the local geology. We aimed to evaluate the information from repeat surveys using identical parameters but different systems to facilitate the understanding of this new type of geophysical data and their application in mineral exploration.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670318438907267","@type":"Researcher","foaf:name":[{"@value":"Marco Antonio Braga"}],"jpcoar:affiliationName":[{"@value":"Vale 1 — Gerência de Exploração Mineral de Ferrosos — Águas Claras — Centro de Tecnologia de Ferrosos — Nova Lima — Minas Gerais State, .
