The aim of the course is to give you the fundamental tools and knowledge to improve your
geological logging by incorporating geochemical and mineralogical data.
This one-day course features a mixture of theory and tutorials and will cover (1) incorporating
geochemistry into geological logging, (2) spectral mineralogy for drill core using HyLogger-3 data and
(3) multiscale analysis and domaining of drill hole data. The course will feature several data analysis
tools including TSG (The Spectral Geologist), ioGas and Data Mosaic (multivariate wavelet
Maximum number of people: 18
Nick will demonstrate how to use geochemical data derived from drilling samples to enhance your
geological logging. He will discuss how to use simple tools from ioGas and Excel to summarise and
visualise your data. Nick has vast experience from logging core all around the world and will provide
you with practical tips to speed up your logging and describe how to focus on the key elements
critical for understanding your mineralising system.
June will show you how to automatically domain your drill hole into litho-geochemical rock units
using your geochemical data. She will give an overview of the theory behind the method for
multiscale analysis (wavelet tessellation) and introduce you to the Data Mosaic web app. You will be
guided through a tutorial using this software to automatically generate litho-geochemical logs at any
Jess will give you a practical introduction to spectral mineralogy using data from the HyLogger-3. She
will demonstrate the use of The Spectral Geologist (TSG) software for visualizing and investigating
drill core spectral data and extracting spectral mineralogy. She will also show you how to access and
download public spectral data sets from Australia’s National Virtual Core Library (NVCL), which is the
world’s largest drill core mineralogical database.
June and Jess will guide you through a tutorial to apply Data Mosaic to simplified spectral
mineralogy, which will help you to accurately log rock units and alteration styles.
Please bring a laptop so you can participate in the tutorials. Temporary TSG and Data Mosaic
licences will be provided to all participants.
