High Resolution Aeromagnetics As And Aid To Geologic Mapping Of Rio Das Velhas Greenstone Belt, Quadrilátero Ferrívero, Minas Gerais, Brasil

A high resolution geophysical survey was acquired in 1992 as a part of Rio das Velhas Project and was used to investigate the regional structural setting of the area and better define lithological boundaries. High resolution geophysical surveying is fundamental to modern geoscientific mapping, providing cost-effective definition of structure and lithology in a diverse range of geological terrains. The airborne magnetic data are particularly valuable for defining northsouth Archean structures and the continuity inside the study area. This paper illustrates the usefulness of the aeromagnetic data in the support of geological mapping in the Rio das Velhas Greenstone Belt.
