The Spectral Geologist (TSG™)

The industry standard software tool for the analysis and mineralogical interpretation of VIS/NIR/SWIR/MIR/TIR reflectance spectra

TSG digitally transforms geological samples into mineralogical information products.

TSGTM is the  market-leading, industry standard software program for the  interactive analysis, visualisation and mineralogical interpretation of VIS/NIR/SWIR/MIR/TIR reflectance spectra. 

Qualitative and quantitative mineral results generated in TSG improve geologists’ efficiency, productivity and knowledge-base, leading to actionable insights and informed decision-making.

TSG works directly with hyperspectral data collected from drill core, chips and field samples acquired by:

  • Compact and portable hand-held infrared spectrometers, including: Malvern Panalytical ASD’s TerraSpec® and Halo, Spectral Evolution’s oreXpress, the Agilent 4300 FTIR spectrometer and the ARCoptix FTIR spectrometers.
  • HyLogger systems, the CSIRO-developed automated imaging and hyperspectral core logging systems, located in each Australian Geological Survey, commercially available for international deployment by Corescan Pty Ltd.

Developed by geologists, for geologists. TSG supports multi-disciplinary geoscientific endeavours across the exploration-mining chain.

TSG is developed by, and marketed under license from, the Commonwealth Scientific Industrial Research Organisation (CSIRO). Spectral Geoscience is a CSIRO authorised sales affiliate of TSG. New timed licensing and pricing options provide flexible options for TSG users to manage the timed access according to project and company needs, removing the upfront costs of software ownership. TSG subscribers receive the latest TSG software updates as they are released.

How To Proceed

  1. Download the free TSG Base licence here.
  2. Install TSG.
  3. Open TSG. Under TSG’s Help->Licence menu; activate the licence, then click ‘Purchase time’.
  4. Your web browser will open on TSG’s online store, purchase the time-block licence to meet your needs.
  5. After the purchase, click Refresh back in TSG’s licence dialog.

TSG’s new licensing system works with an online licence server.  Licenses are available 24 hours a day and purchases are made online by Visa or Mastercard.  You can have TSG installed and licensed in a few minutes.


We provide international support for TSG users via
phone, email or online meetings.


We provide onsite and online training for:
1. Introduction to infrared mineral spectroscopy
2. Workflow methods and operational use of handheld infrared spectrometers for efficient hyperspectral core logging and field mapping.
3. How to use TSG to maximise the mineralogical information from your spectra, integrate with ancillary data and generate mineralogical products (maps and logs).

TSG is used by companies around the world including:

More about TSG™

Identifying the mineralogy in drill core, chips, soils and grab samples is a primary objective for successful mineral exploration, mine planning and development, geometallurgical flow sheet design and environmental-remediation practices. TSG supports geoscientists at each step in the exploration-mining value chain by providing rapid characterisation results of infrared-active mineralogy to generate actionable insights. Complimentary datasets such as assays, lithology logs and down-hole geophysical results, can be imported to evaluate the spatial relationships with the spectro-mineralogical results generated in TSG. TSG can process thousands of spectra on-the-fly and rapidly generate mineral information critical for the characterisation of the regolith, host rock and alteration associated with ore deposits. TSG is designed for the interactive analysis and visualisation of infrared spectra, mineralogical results, associated imagery and ancillary data. Users are provided with several analysis options for extracting mineral information from infrared spectra. These range from a first-pass automated interpretation using built-in algorithms to more sophisticated scalar-based tools for the experienced user.

TSG Version 8 contains:

    TSG version 8 replaces all earlier versions (e.g. TSG Pro, Core, HotCore and Enterprise) and bundles the previously separated functionality into one powerful package, TSG 8. There is now only one ‘TSG’ and the free ‘ TSG Viewer’.

    TSG8 includes NEW:

  • Algorithms for the automated interpretation of spectra (TSA+ for the SWIR and jCLST for the TIR).
  • Improved spectral libraries.
  • Enhancements to take full advantage of VNIR-SWIR+TIR data collected with HyLogger hyperspectral core logging systems.
Results generated from TSG can include:
  • Mineral identification
  • Relative abundance
  • Crystallinity
  • Compositional changes within a mineral group (e.g. Al-Fe/Mg in white micas and Fe-Mg in chlorites).
Products generated can include:
  • Down-hole, depth-registered logs of mineralogy and associated attributes (alpha and numeric formats).
  • Scatter plots and histograms saved as JPG, PNG, EMF and TIF.
  • CSV files exported for easy integration with third party software. Down-sampling optional (e.g. 2m composites).
  • HyLogger imagery export of automatically configured and labelled core trays and mosaics of core trays per drill hole.
TSG Software Description and Hardware Requirements

TSG (The Spectral Geologist) is a menu and icon-driven, 32-bit Windows program written in C on the Win32 API. It runs on 32- and 64-bit x86 Windows, versions 7 to 10. Although TSG is a 32-bit program, it runs better on 64-bit Windows than 32-bit. Windows-XP is no longer supported.

Aside from a few system controls and dialogs that Windows displays in the host PC’s language, TSG’s interface is in English. However it has been installed and used on non-English Windows PCs including Spanish and Chinese.
TSG has no particular hardware or software requirements. It has been used on x86 Windows PCs ranging from small AMD field notebooks to multiprocessor i7 desktop PCs. TSG is threaded and will take advantage of multiple processors if present.

TSG communicates with a USA-based licence server https://secure.softwarekey.com over the internet on ports 80 (HTTP) and 443 (HTTPS). Although it is possible to set up and use TSG on an isolated PC, intermittent internet access (at least) is highly recommended.

The recommended minimum hardware requirements are:
1.0 GHz or higher CPU
512 MB or higher RAM
600 MB or higher of free disk space
Microsoft® Windows® 7 or higher
800 x 600 or higher graphics resolution 24-bit colour or better’.

TSG 8 is not backward compatible

Once a dataset is opened in TSG 8, it can no longer be opened in a previous version of TSG. Learn More
