GMEX is a series of 8 spectral analysis guides, including a spectral library that have been developed by AusSpec to provide mineral exploration and mining geoscientists using PIMA, Terraspec, Fieldspec and airborne Hyperspectral data with specific and detailed assistance in the use of spectral data in specific geological environments.

The GMEX guides have been designed primarily to serve as a quick, practical and comprehensive reference for geoscientists involved with the analysis of infrared reflectance spectra. The guides focus on mineral exploration and mining applications.

• Real Exploration Data
• A comprehensive resource
• Latest analysis techniques
• Problems and solutions
• Digital data sets

GMEX has been designed to present real exploration spectral data in a geological context and their significance to particular alteration styles/facies, rather than simply as an exhaustive listing of pure mineral spectra.

By presenting this type of data aids geologists to interpret their own spectral data sets and more importantly, allows them to recognise the indicators of alteration related to potentially economic mineralisation with greater confidence.

Each major topic covered in the volumes is listed in the comprehensive index located at the back of every volume. Text on each topic is supported by clear, easy to understand figures showing example spectra. The spectra shown in each figure can also be examined in more detail by viewing the GMEX digital data set.
 

GMEX Volumes

Volume 1: Spectral Interpretation Field Manual

The Spectral Interpretation Field Manual contains a practical spectral library consisting of examples of commonly encountered mineral groups as well as tips on how to recognise their diagnostic spectral characteristics. It also contains background information on reflectance spectroscopy and a step by step guide to identifying pure and mixed mineral spectra including notes and examples of spectral variations due to compositional and crystallinity variations within important mineral species.

GMEX Volume 1 is now in html format and can be browsed and searched on CD.
 

Volume 2: Practical Applications Handbook

The Practical Applications Handbook contains information relevant to all spectral analysis projects, irrespective of the style of mineralisation or geologic environment. It contains background information on a wide range of data collection and analysis techniques including notes on the influence of sample type and carrying out quantitative analyses. It also contains detailed practical advise on the use of PIMA spectrometers including trouble shooting tips, basic information on how to set the instrument up and how to measure and store spectral data.
 

GMEX Volumes 3-8

These contain detailed information on the important characteristics of mineral spectra in relation to each specific setting. Each guide is logically subdivided into chapters either on the basis of alteration styles and facies or, in the case of volumes 5 and 8, on the basis of lithologies, weathering characteristics and dominant clay type in regolith units.

• Volume 3 - Porphyry Alteration Systems ~104 pages
• Volume 4 - Epithermal Alteration Systems ~86 pages
• Volume 5 - Near Surface Weathering Environments ~86 pages
• Volume 6 - Archean Greenstone Gold ~86 pages
• Volume 7 - Volcanic Hosted Massive Sulphide Systems ~56 pages
• Volume 8 - Regolith Logging ~90 pages
