description | The characterization of shear zones at the southern portion of the Ribeira Belt, PR, BR, as well as its recognition in depth
is a major challenge. Despite the lack of subsurface information, the influence of such structures on the installation and
evolution of the Paraná Basin during the Phanerozoic is widely accepted. Therefore, in this paper, are applied methods
of anomaly enhancement (qualitative analysis) and estimative of the sources depth (semiquantitative analysis), on the
aeromagnetic coverage of the Lancinha Shear Zone area (LSZ) in the Paraná state, in order to verify its spatial arrangement
in subsurface. The processing resulted in the interpretation of magnetic-structural framework of the study area, which
was validated by the depth estimative of the magnetic sources (Euler solutions). The results indicated the extension of the
Lancinha, Morro Agudo and Itapirapuã shear zones under the Paraná Basin coverage. |
