This subject deals with methodologies for extracting geological information out of geophysical datasets. The subject mostly covers potential fields (gravity and magnetic methods) because these datasets are readily available, however it also visits seismic and electrical geophysical methods. GEOL30005 focusses on physics concepts and how they can be used to understand geology. Students work with industry standard software (eg. Geosoft - Oasis Montaj) which performs the maths in the background.
Topics covered include maps, projection systems, datums and GPS; theory, acquisition, processing and interpretation steps involved for gravity and magnetic methods; image enhancement and qualitative interpretation techniques; quantitative style 2.5D geophysical modelling; seismic theory, acquisition, processing and how this integrates with geophysical wire-line well logging; radiometric acquisition/interpretation; and electrical geophysical techniques such as resistivity, induced polarisation, self-potential, electromagnetics and magnetotelurics.
Intended learning outcomes
After completing this subject, students will have acquired a basic understanding of applied geophysics, including the acquisition, processing, modelling and interpretation steps involved for gravity, magnetic, seismic and electrical methods.
