What is The Spectral Geologist?

TSG represents the combination of years of research into the analysis of spectral data and the commercial application of spectral analysis in a wide range of mineral exploration and mining environments from around the world, as well as in academia and State Agencies.

TSG has revolutionized the way geological spectral data are processed and analysed. Spectra are not treated in isolation, but as a project data set with all the ancillary project data combined and organised together with your spectral data. This means that spectral data can easily be analysed in the context of the project geology, and contribute directly to understanding the alteration and mineralisation relationships in the project area.

TSG organises all your spectral data (from 10s to 10,000s of spectra) into a single file structure allowing the data and analysis results from a single project, drill hole or geochemical grid to be stored and analysed together with an interface that has been designed specifically for geological applications.

TSG8 has seven screens and two floater windows allowing the user to examine their data set at various levels of detail, from the level of individual sample spectra to broad overviews and spatial plots containing thousands of spectra and associated data. To see some of the various screens go to the TSG screens page.

Its main features include:

TSG File Structure: Each TSG file can contain all spectra from a single drill hole or a whole series of drill holes from a project area. In addition, ancillary data relating to the samples/spectra can be imported into data slots into the TSG file structure, and the results of processing and calculations on the spectral data will also be saved into data slots in the TSG file all as TSG Scalars. This means that all project data can be compared together, and your spectral data analysed in the context of your project geology.
TSG Screens: There are seven different screens in TSG, each offering you a different way of looking at your spectral and ancillary data. See the links above for more detail on each screen’s capabilities.
TSG Display Tools: Using the TSG screens, the spectral and ancillary data from all samples/spectra can be compared using the many different display options available in TSG. Allowing you to analyse not only the mineral assemblages of each sample and how these vary down hole or in a project area, but also look at specific variations in mineral characteristics down hole, between holes or over a project area. Examples of plotting and analysis of results are presented in the discussions on each of the TSG Screens.
Automated Identification: TSG features two different approaches to automated interpretation: The Spectral Assistant and Aux Match. These are designed to assist you in interpreting your project spectra and are covered in more detail under the discussion on Automated ID.
Spectral Maths: The Spectral Maths options in TSG offer many different methods for processing your spectral data and calculating specific characteristics of your spectra that may relate to a mineral characteristic, such as the wavelength of a diagnostic absorption relating to mineral composition. The results of this processing can then be plotted alongside ancillary data in the Log or Scatter screens for in depth analysis of your alteration system.
Copy Processing: Once you or a spectral expert have processed a data set as part of a pilot study on a project area, for example, the processing methods built into the processed TSG file can be used as templates for any more spectral data and TSG files that you may measure and build for your project area.
Import and Export: Numeric and text (class) data can be imported into your TSG file from a csv (comma delimited) file or the clipboard. All processed data can also be exported to csv files for plotting in other plotting packages. In addition, the graphics of all plots can be copied and pasted into other packages, which makes report writing easy.
Inbuilt Reference Library of spectra of common minerals. As well as the mineral spectra the library also includes some artefact materials such as vegetation, plastic and marker pen which could also potentially contribute to your project spectra.
