Applied Geophysics - Magnetic Anomaly Data Mosaic of the Socorro-Guaxupé Geological Area (Brazil)

<p>The Socorro-Guaxup&eacute; area is a complex structural environment formed during Proterozoic times, associated with the formation of the Gondwana Supercontinent. The notable magnetic signatures of these geological areas were selected for an Applied Geophysical project for undergraduates in the Geology Course at the University of S&atilde;o Paulo in 2024.</p> <p>This grid mosaic encompasses airborne magnetic data from areas 15, 14, 7, and 2 of the CODEMIG repository (<a href="http://www.codemig.com.br/" target="_new" rel="noopener">http://www.codemig.com.br/</a>) as well as data from areas 1105, 1117, 1039, 4099, 4112, and 4210 from the Geological Survey of Brazil (SGB-CPRM). The surveys were gridded with cell sizes of 1/4 of the flight line spacing, using the minimum curvature method. Additionally, they were continued to a nominal altitude of 700 m for decreasing noise signal, due to the variable spatial resolution and acquisition techniques. Grid stitching was performed using pairs of grids, with the stitching method implemented in Oasis Montaj software. The locations of all surveys are presented in the figure "socorro-guaxupe_surveys.tif."</p> <p>We would like to thank the team at the Laboratory for Research in Applied Geophysics (LPGA) and the professors from the Rio de Janeiro State University (UERJ) and GeoAtlantico Institute for their technical support in assembling this data.</p> <p>This study was financed in part by the Coordena&ccedil;&atilde;o de Aperfei&ccedil;oamento de Pessoal de N&iacute;vel Superior - Brasil (CAPES) - Finance Code 001 (L.
