    Understand Earth’s formation, evolution and structure using project-based applications of geophysical theory, including seismology, gravitation, magnetics and electromagnetics.

    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.

    Paper Structure

    Lecture topics are:

    1. Physics of the Earth (1 week)
    2. Gravity (2 weeks)
    3. Magnetism (2 weeks)
    4. Electromagnetic Methods (2 weeks)
    5. Geophysical Field Methods (1 week + 2-day weekend fieldschool)
    6. Seismic methods (4 weeks)
    7. Geophysical Inversion

    Assessment is typically split between internal (ongoing during the semester) and external (final exam).
    Assessments for GEOL361 are set and graded differently to GEOL261 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.
