Interpretation

The interpretation of geophysical results into meaningful geological parameters is the prime function of any interpreter. The manipulation of geophysical data is only a means to an end, and the final product of the interpretation is the compilation of a series of maps showing interpreted geological parameters. 

The data processing routines and mathematical operators applied to the data by McPHAR are not the end product of the interpretation; they help delineate geologic and economic targets to be discussed in the final report. 

Many techniques are available to apply to an interpretation project; to determine depths to causative sources, to delineate discontinuities and boundaries, and to draw conclusions regarding geological structure beneath the survey. 

A wide variety of contour and interpretation maps, profiles, cross-sections and models, and a written report are usually the result of the interpretation.

 

Generally, the following steps are followed during an interpretation project:

  • Background research
  • Study of the geophysical data to be interpreted
  • Further data processing to enhance data
  • Data presentation
  • Modelling
  • Preparation of interpretive maps and sections
  • Documentation of conclusions
  • Report preparation

We realize that the data interpretation is a key component in maximising the usefulness of airborne geophysical data. As a consequence, at McPHAR interpretation projects are carried out by experienced geophysicists. We believe that the three main aspects of any interpretation are, 1) methodology, 2) tools and 3) the interpreter.
