Due to COVID-19 restrictions, a selection of on-campus papers will be made available via distance and online learning for eligible students.

Techniques and interpretation of seismological, gravity and magnetic studies; geophysical determination of the structure of the crust, mantle and core; thermal budget of the earth and the driving forces for plate tectonics.
Through acquisition, reduction and interpretation of data from their own local
geophysical surveys, students will become familiar with the use of geophysical methods
in understanding the near surface. Students will gain field experience with seismic,
gravity, magnetic and electrical geophysical techniques. We will utilise Web- and
computer-based tutorial sessions for reduction and interpretation of the local surveys.
Using the knowledge gained from local practical studies we then examine larger New
Zealand and international geophysical data sets to investigate the structure of the
Earth generally and specifically the geophysical signatures of petroleum mineral resources.
The second aim of the course is to examine more deep-seated processes that
govern the dynamic behaviour of the Earth. We shall investigate the physics of forces
that drive core and mantle flow, earthquakes, mountain building and fluid flow. Simple
modelling techniques are introduced so that students can perform simulations of the
Earth's thermal and mechanical behaviour. Students who complete this course should
have a working knowledge of the practical application of geophysical methods at scales
appropriate for exploration of mineral resources, evaluation of petroleum basins and
also to the larger scales of determination of Earth's structure.

Lecture topics are:
- .Physics of the Earth (1 week)
- Gravity (2 weeks)
- Magnetism (2 weeks)
- Electromagnetic Methods (2 weeks)
- Geophysical Field Methods (1 week + 2-day weekend fieldschool)
- Seismic methods (4 weeks)
- Geophysical Inversion
Assessment:
Assessment is typically split between internal (ongoing during the semester) and external (final exam).Assessments for GEOL 361 are set and graded differently to GEOL 261 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
- Teaching Arrangements
Two lectures and one 3-hour laboratory per week.
Fieldwork: A short weekend fieldschool will be undertaken to gain experience in collecting a range of geophysical data sets. These data will then be analysed during subsequent laboratory sessions.
