Magnetic Framework Of The Borborema Province, Northeast Brazil: An Interpretation From Digital Data

A total field anomaly - magnetic grid, available by South American Magnetic Mapping Project, was filtered in the Fourier<br>Domain to separate shallow and deep crustal magnetic sources. The colorful - shaded maps were correlated with known<br>geological data of the Borborema Province, Northeast Brazil. This correlation demonstrates that several shear zones,<br>lithologic boundary and tectonostratigraphic terrane have strong affinity with magnetic patterns and lineaments. As a<br>result of this integrate study a consistent magnetic framework of the Borborema Province was constructed, as a help to<br>terrane analysis and metallogenic researches.
