The Spectral Geologist (TSG™)

Mineral Analysis Software

Designed to assist TerraSpec® 4 mineral analyzer users to quickly and accurately identify key minerals in a deposit, The Spectral Geologist (TSG™) mineral analysis software uses the high quality spectral data captured using the TerraSpec 4 mineral analyzer to easily sort and analyze mineral data. In addition to the software’s intuitive flow and visual presentation of complex data, it offers

  • Highly visual interpretation of spectral data, with a variety of visualization options
  • The ability to turn thousands of spectra into mineralogical indices for plotting mineral characteristics (such as composition)
  • Tools to assist with automatic mineral interpretation, such as The Spectral Assistant® (TSA™) and the Aux Match function
  • The capacity to analyze and visualize the mineralogy of large core-logging data sets
  • The capability to see and plot your results down hole, or as sections, maps and scatterplots
  • Simple export of critical data which can be used in other software programs for further processing

Below: The TSG Scatter Screen. Here we have a spatial Easting vs. Depth plot showing about 40 drill holes together with a scatter plot of two spectral indices calculated from the spectral data. Each circle represents a sample point. The Lasso function is illustrated here, where a cluster of sample points have been lassoed in the scatter plot and their spatial positions in the Easting vs. Depth plot are highlighted.

Developed by the Commonwealth Scientific Industry Research Organization (CSIRO) in Australia, the TSG software interface has been designed specifically for geological applications. The analysis techniques available in TSG focus on the applications of using spectral reflectance data for mineral analysis of outcrops, hand samples, drill cores, chips and pulps. Project data sets can be combined and organized together to easily analyze using methods such as mapping mineral assemblages, applications of spectral parameters for automated logging/mapping, deposit characterization and developing vectors to mineralization.

Below: The TSG Log Screen.  In this plot, the spectral analysis results (Grp1 TSAS, Grp2 TSAS, CompChlorite, CompWtMica and dAlOH/dMgOH) are compared with imported data on each sample (Hole ID, from-to depths, and mineralisation percentage).  The spectral data provide useful data on the key minerals which compared with the imported mineralisation data indicate a distinct change in both the chlorite and white mica chemistries which appears to be directly associated with proximity to mineralization.

Global sales, support and training for ‘The Spectral Geologist’  (TSG™) software is now available through Spectral Geoscience Pty Ltd.

New release TSG 8

Cost-effective, flexible, time-block licences of the newly released TSG version 8 are now available via a secure online sales portal. TSG 8 contains new functionality, an updated spectral library and improved processing algorithms. Contact Spectral Geoscience for more information and pricing.

Spectral Geoscience can assist you in utilising ASD spectrometers and the TSG software as tools to extract qualitative and quantitative mineral information from geological samples to support the objectives of exploration geologists, mine geologists, geotechnical engineers, geometallurgists and environmental scientists. 

TSG assists Halo users with:

  • Custom import for Halo data, associated scalars and GPS coordinates.
  • Functionality to construct additional scalars.
  • Interactive visualization of the spectra, mineralogical information (plan view and down-hole plots) and linked core/chip/field sample photos.
