Ensaios De Polarização Induzida Espectral (Sip) Aplicados À Exploração Mineral De Chumbo E Zinco No Alvo Paqueiro, Vale Do Ribeira-Pr

This paper shows the results of the Spectral Induced<br>Polarization (SIP) traverses run across Mobile Metal<br>Ion (MMI) Pb-Zn-Cu-Cd geochemical soil anomalies<br>at the Vale do Ribeira region (Paraná State).<br>Inversion of the apparent chargeability defines strong<br>polarized bodies that are coincident with most of the<br>soil geochemistry anomalies. The time constant<br>spectral parameter allow us to suppose that the high<br>chargeability targets that were not related to soil<br>geochemistry anomalies could represent other<br>polarized minerals than sulfides.
