Processamento e interpretação de dados aeromagnéticos da região central do Arco de Ponta Grossa (Bacia do Paraná)

Abstract

Residual aeromagnetic data arranged into regular 500 x 500 m grids from 2-km-spaced N-S, 450 m high flight lines were microleveled and processed. The horizontal gradient, analytical signal amplitude and phase and Euler deconvolution maps were qualitatively interpreted. The results led to the establishment of a structural –magnetic framework for the central portion of the Ponta Grossa Arch (Parana Basin, Brazil), where prominent NW-SE structures reflect a thick swarm of diabase dykes, as well as other secondary NE-SW and E-W trends (N-S trend were revealed from digital elevation model).
