An EGRU Professional Geologist Short Course

Integrating Geochemistry & Mineralogy for Exploration

Course Leader: Dr Dennis Arne, CSA Global



Sunday 28 April 2019



James Cook University, Townsville Campus


Delegate numbers are limited.

Geochemical and mineralogical data are now routinely collected on the same sample material, but the interpretation of these data sets is often done separately. Geochemical data may include assays or multi-element data collected from crushed rock or from surficial material. Mineralogical data may include hyperspectral analyses, semi-quantitative XRD or heavy mineral separates. Integration of complementary data sets such as these on a single interpretive platform allows for a better understanding of geochemical and mineralogical processes associated with hydrothermal mineralisation and secondary dispersion.

The short course will be a full day of lectures, discussions, and practical interpretive exercises. Participants will need to bring a laptop computer and download a demonstration copy of ioGAS software. Lectures on geochemical and mineralogical responses from some common hydrothermal deposit types will be integrated with exercises involving data interpretation. Topics covered will include:

  • Introduction to the integration of geochemical and mineralogical data
  • Introduction to exploration data analysis (exercise)
  • Review of hydrothermal alteration systems
  • Defining hydrothermal alteration using geochemical data (exercise)
  • Introduction to mineralogical data in mineral exploration
  • Case studies illustrating data integration
  • Data integration exercises

Dennis Arne has over 35 years’ experience as a geologist and geochemist, working in a wide range of commodities and environments. In recent years he has consulted to exploration programs for precious and base metals exploration in Australia, North America, South America and the Middle East. This has included the design and implementation of geochemical surveys, the interpretation of geochemical data, the design of QAQC programs, reviews of geochemical data quality, and training of personnel. He has published extensively in the areas of applied geochemistry and economic geology.
