EGRU Online Short Course: Exploration Geophysics for geologists

Date & Time

22 – 23 – 24 March 2021
9.30am – 1.00pm  (AEST)  3.5hr sessions each day (including a breaks)
 

This short course will be presented by a team of expert geophysicists with extensive experience in applying geophysics in exploration.

The course will provide an overview of the main geophysical methods used in mineral exploration and the application of these methods in an exploration program.  Course participants will gain insight into basic theory, applications of the different methods to various geological settings, methods of data acquisition, processing and interpretation, and how to communicate with contractors.
