Uchoa, Elenilton Bezerra; Duarte, Cynthia Romariz; Magini, Christiano; Mirianda, Mateus de PaulaRecently the state of Ceará, Brazil, has been an important iron ore producer and exporter, by Bandarra mine in Quiterianópolis city. In this city there are five known iron occurrences named Calixto, Bandarra, São Francisco, Olho D’água and Pintada. The Bandarra iron ore deposit produced and exported from Brazil to China about 1.2 million tonnes of iron ore with 60% content. These iron ore are located in Norther...

Uchoa, Elenilton Bezerra; Magini, Christiano; Castelo Branco, Raimundo Mariano Gomes; Silva, Nilton Cesar Vieira; Silva, Fabiano Mota daSince the 1950s, the magnetotellurics method (MT) has been widely used in mineral and oil prospecting (sedimentary basins), cratonic regions and recognitions of crustal-scale geological discontinuities. MT geophysical method consists of a passive technique that aims to investigate geoelectric characteristics of subsoil through the interaction between telluric currents and subsurface materials. The objective of ...
