Radargrams

These are geophysical interpretations of the data. The below image is a Radargram, delivered in section form with distance on the x-axis, and depth on the y-axis. Data can be refined using algorithmic filters to highlight key areas of interest. The radar looks only directly down from the antennas, recording data every step.

Analysis

Data is collected by the operator and downloaded into a laptop for analysis on proprietary software.

Data is processed through the use of algorithms and settings that are used to highlight certain conductive and resistive properties of the sub-surface lithology.  The structural heterogeneity of the profile is visible, as each radar pulse – taken every 20cm – is “stacked” to make a geological picture. 

Our analysis is  guided by the geological data provided by the client to calibrate to geophysical boundaries.  When we have “hard” or real data in the form of drill-data or visual data, we can interpret the geophysical boundaries seen in the radargram with confidence and certainty, and make reasonable inferences from one known point to the entire profile.

So from one point of reference on the profile, as we are able to review the geo-electric properties of the material, we can “track” the target mineral across the whole profile. So one drill hole can be used to “reveal” information across a much larger area. Hence the ability to use less drilling in exploration.  

Analysis – Use of Algorithms to show different properties on the same profile.

As the slide opposite shows, on profile collected by Loza Radar, can reveal different features in useful ways. In this case, the client can see: (1)  Location of mineralisation, (2) Structure & (3) Water

Software

As a result of the increased power and sophistication of the data collected, Loza Geophysics has developed specialist software for processing and analysis.

The data can also be provided in the following formats:

  • RAW file

  • TXT file

  • 3D Model where appropriate

  • Other formats available upon request
