Title: New Previous HitComputerNext Hit-Oriented Technique for Interpreting EM Anomalies: ABSTRACT

Author(s): Steve Bauer

Article Type: Meeting abstract

Abstract:

A geophysicist may improve his interpretation of EM (electromagnetic field) data by following four steps. (1) Noise and near-surface contributions are identified and subtracted from data by a high-speed digital Previous HitcomputerNext Hit. (2) A three-dimensional sketch of an ore deposit is interpreted by the geophysicist from characteristic data variations. (3) The data are then compared with fields previously calculated by a Previous HitcomputerNext Hit for model conductors. (4) The closest model is modified to fit the sketch and is further modified by a Previous HitcomputerTop to duplicate the data most closely, thereby giving a detailed three-dimensional picture of the ore deposit.
