A Better Understanding Of Exploration Geochemistry
1 day | $500 + gst
Multi-element geochemistry is one of the most powerful tools available to an exploration geologist; it is also a tool that many skilled and seasoned practitioners struggle with day to day.
Designing effective geochemical sampling programs, managing large multi-element databases, and correctly interpreting the data are critical disciplines for an exploration geologist to master.
To explore effectively, we must integrate a diverse range of data; but geochemistry is the one dataset that directly identifies (and quantifies) mineralisation. Therefore, it warrants special attention!
Critical issues facing clients when managing and interpreting their geochemical data will be addressed in this course. Although it is not intended as a comprehensive ioGAS training course, participants will gain a working knowledge of this software learning how to use many of its functions.
Upon completion of this course, you will have a solid grounding in ten important skills in Exploration Geochemistry. You will be able to:
- Validate data, and recognise the limitations of that data;
- Use X-Y plots to explore data, validate results of more advanced investigations and link to spatially defined anomalies;
- Identify element associations in your data using Principal Component Analysis;
- Recognise that element associations are scale dependent;
- Break false correlations in your data using Centred Log Ratios;
- Understand the advantages of using probability plots over histograms;
- Construct a log-additive index that highlights an anomalous metal association;
- Use alteration geochemistry to better understand the mineralogy of a hydrothermal alteration system;
- Discriminate different rock types using immobile element ratios;
- Apply immobile-incompatible element ratios to define separate magma series (or sediment packages).
Our facilitator is an experienced practitioner with a robust mix of academic and practical expertise.
DR CARL BRAUHART
PHD MAIG MSEG
Carl is an exploration geologist with over 25 years experience in gold and base-metal exploration, spending much of that time working in frontier areas of Western Australia on grassroots projects. He has a particular interest in exploration and ore deposit geochemistry, and a passion for field work, particularly mapping. Carl has maintained a close association with the Centre for Exploration Targeting at the University of Western Australia where he is the lead researcher on the OSNACA Project (an ore deposit geochemistry research effort). During his time at CSA Global, Carl has undertaken fieldwork across Australia, Sudan and Uganda and has carried out major geochemical investigations for many mining clients on gold, base-metal and industrial mineral projects globally.
Who is this course for?
This one-day course is designed for moderately to highly experienced exploration geologists who wish to extend their skills in geochemistry. Knowledge of ioGAS is not required. Our facilitator will work systematically through each exercise, allowing time for note taking by participants.
This course is available on-site or as a customised training.
“I’ve been doing geochemistry data interpretations for over 25 years, but still learned a lot from Carl’s course. Especially the new methods and the use of must-have software, ioGAS. Thanks to this course, I’ve just completed a major geochemistry data review for a client which was very well received. Carl’s workshop is gold.”
