New instrumentation for large 3D electrical resistivity tomography and induced polarization surveys

Driven by needs of mineral exploration for ever faster and ever easier setup of large 3D resistivity and induced polarization, autonomous and cable-free recorded system come to the forefront. Today, these are used for many others applications than mining exploration – geothermal exploration, urban investigation, etc. Contrary to the traditional centralized acquisition, these new systems allow a complete random distribution of receivers on the survey area for obtaining a full-3D resistivity and chargeability tomography. Several proprietary full-3D systems are used by their owners for service work in many mining focused places (South America, China, Australia, etc). But very few are today accessible on the market allowing nor public either private entities to perform their own survey.
