MAPPING INDUCED POLARIZATION WITH NATURAL ELECTROMAGNETIC FIELDS FOR EXPLORATION AND RESOURCES CHARACTERIZATION BY THE MINING INDUSTRY

[摘要] In this quarter we continued the processing of the Safford IP survey data. The processing identified a time shift problem between the sites that was caused by a GPS firmware error. A software procedure was developed to identify and correct the shift, and this was applied to the data. Preliminary estimates were made of the remote referenced MT parameters, and initial data quality assessment showed the data quality was good for most of the line. The multi-site robust processing code of Egbert was linked to the new data and processing initiated.
