Geological Interpretation of Aeromagnetic Data – a Practical Approach

2-Day Online Workshop, 1st – 2nd August 2022

(Limited to 30 places)

NExUS-Professional Development (NExUS-PD) is proud to be able to present this very highly regarded workshop online for the very first time.
• The specially designed two-day online workshop* will introduce the fundamentals of geological interpretation of aeromagnetic data.
• The workshop will feature lectures, practical activities and case studies all using integrated data sets.
• Each day will feature 3 x 2hr sessions with exercises to be completed between the sessions and time allocated for extended discussions.
• The format aims for open, transparent communication, with input from participants highly encouraged to share knowledge and experiences.
*This is a level-4 course (honours level) and is designed to be suitable for early career geoscientists, honours students and HDR students. The workshop is not assessed.

Day 1, Methodology of Aeromagnetic Interpretation – David Isles (1st Aug) :
• Sessions will include: Basic Principles, Physics and Concepts of Magnetics, Spatial Concepts, Survey Planning, Processing and Presentation of Data, Anomalies, RTP and Analytical Signal, Modelling and Inversion, Introduction to Golden Dyke Prospect Case Study
Day 2, Geological Interpretation and Structure – Leigh Rankin (2nd Aug) :
• Sessions will include: Golden Dyke Prospect Case Study, Magnetisation in Rocks, Charters Towers Case Study, Structures in Magnetics, Widgiemooltha Case Study, Unusual Magnetisation and Final Q+A session.

Overview:

Adrian McCallum has dabbled in geophysics for decades; as a sensor operator on Navy Seahawk helicopters or as a glaciologist measuring ice characteristics in the Arctic or Antarctica. In this brief discussion, he reflects on his diverse geophysical and geotechnical work till this time and introduces future opportunities to employ geophysics, across a diverse range of environments.

Abstract:

Last century, Man set foot on the moon and shortly after, in 1972 the first satellite was launched with the express intent of monitoring our planet's landmasses. Over the following decades, technology advanced and the applications for using Earth Observation also grew. In 2022, Satellites no longer need to weigh the same as a sedan and cost a billion dollars to design, build and launch. With advances in technology leading to miniaturisation and the arrival of ride sharing launches, space is now accessible to almost anyone with passion, a good idea and a pitch to venture capitalists. In this presentation, I will take us on a brief history of satellite evolution and lead us into a discussion on using Short Wave Infrared and other wavelengths for mineral exploration. We will look at using tri-stereo optical imagery to generate more accurate DEMs, discuss how radar can be used to see geological structures and how the phase component of radio waves can be used to measure changes at the scale of mm, and how this method can be used for monitoring hydrocarbon basins and mine induced subsidence. Finally, I will offer a glimpse of the future, of some of the new satellite startup companies and how those technologies will change our view of the world.
