The Graduate Diploma of Geoscience provides an advanced degree that allows students to undertake further study so that they have a solid geoscience background to gain work in geoscience exploration fields. The Department of Earth and Planetary Sciences at Macquarie University has an international reputation for its multidisciplinary research and study programs, with expertise in geology, geochemistry, geophysics and geodynamics. These fields are critical to understanding many environmental and industry-related problems. Unique to this degree is its multidisciplinary and “big-picture” problem-solving approach, necessary to tackle 21st century problems. Our teaching is also supported by the world-class ARC research centre Core to Crust Fluid Systems and various other high profile research groups. All students will be assigned an academic advisor within the Department of Earth and Planetary Sciences who will assist the student, before beginning the diploma, in planning a course of study appropriate to his/her area of interest.
