GESSL Libraries

The Geological Environment Specific Spectral Libraries (GESSLs) have been designed to make spectral geology more accessible for non-experts.  The aim is for users to be able to focus on the information gained from the spectra, rather than getting caught up in the analytical process.

What is GESSL?

• GESSL is a new series of geological environment specific spectral libraries made up of spectra of mineral assemblages from a variety of geological settings.

• GESSL is the engine of the The Spectral Expert template files (TSE) which allow users to process a broad range of mineral assemblages found in many different deposit styles.

• Using GESSL and The Spectral Expert templates with TSG allows users to automatically process a spectral data set of 1000's of spectra within a few minutes.

• The output from GESSL and TSE files is similar to the output that would be produced by a spectral expert, and provides users with rapid access to a complete analysis of their spectral data.
   

GESSL Geological settings

GESSL's have been and are currently being developed for a number of geological settings. In particular:

• Epithermal systems
• Porphyry systems
• Lateritic regolith profiles
• Archean greenstone settings

Is GESSL easy to use?

The GESSL files can easily be used as comparative spectral libraries to overlay with your project spectra.

However, they are more effectively used as the training library for the Aux matching process utilised by the Spectral Expert files.  In this way the TSE files automatically matches your project spectra against the GESSL spectra and outputs the interpretation.

Project specific GESSLs

AusSpec can build your own project specific GESSL for an advanced project area/deposit to assist you in routinely mapping key alteration minerals and mineral assemblages. 

This is a service already being used by many clients with a high degree of success.
