GMEX Guides for Mineral Exploration Edition 3

GMEX Ed3 Includes
10 Volumes
~1000 pages of text and figures
Digital Spectra

GMEX is a series of 10 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 3rd edition of the GMEX manuals now comprise 10 technical reference manuals and also include discussions on the vis-NIR-SWIR spectral response of common minerals and mineral mixtures typically encountered with various spectrometers.  The 3rd edition has been completely revised and incorporates new information of spectral mixtures and up to date spectral analysis techniques.  In addition, the 3rd edition incorporates two new geological settings: SEDEX and Iron Oxide Copper Gold.  These two new volumes are a product of two separate industry sponsored research programs investigating the spectral response of minerals in these deposits. 

The new GMEX Edition 3 includes:

• Volume 1 - Spectral Interpretation Field Manual
• Volume 2 - Practical Applications Handbook
• Volume 3 - Porphyry Alteration Systems
• Volume 4 - Epithermal Alteration Systems
• Volume 5 - Near Surface Weathering Environments
• Volume 6 - Archean Greenstone Gold
• Volume 7 - Volcanic Hosted Massive Sulphide Systems
• Volume 8 - Regolith Logging
• Volume 9 - SEDEX systems
• Volume 10 - Iron Oxide Copper Gold (IOCG)

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 in each 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.
 

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 advice on the use of various spectrometers including trouble shooting tips.
 

GMEX Volumes 3-10

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 or facies or, in the case of volumes 5 and 8, on the basis of lithologies, weathering characteristics and dominant clay type in regolith units.
