Why is this course for me?

Geology is the study of the earth: the nature and origin of materials that make up our planet and the natural and energy resources it provides. It explores the processes that shape the earth (e.g. climate change, earthquakes, volcanoes and landslides). Geology addresses fundamental questions regarding the structure, age and evolution of the earth, its controlling processes and the history of life. Geology impacts profoundly on many aspects of life and society.

Career & Graduate Study Opportunities

Geology graduates work in areas essential to understanding and protecting the environment, in industries using natural resources and developing infrastructure in roles such as geological surveyors, petroleum and mineral exploration and production geologists, mine geologists, hydrogeologists, oceanographers, geochemists, environmental consultants and engineering and structural geologists.

Graduates can also pursue a range of MSc or PhD opportunities in Ireland or abroad. Graduate programmes include the UCD MSc in Petroleum Geoscience, and programmes offered by several UK universities include MSc in Hydrogeology, MSc in Engineering Geology, and MSc in Oceanography.

What Will I Study

This is a sample pathway for a degree in Geology. Topics include sedimentology, palaeobiology, geochemistry, volcanology, petrology, geophysics, structural geology, tectonics, earth evolution, earth resources and applied geology.

First Year

  • Geology
  • Mathematics
  • Optional Science modules
  • Elective modules

Second Year

  • Geology (includes a residential field course in the west of Ireland)
  • + 1 Other Science Subject
  • Elective modules

Third Year

  • Geology (includes residential field courses in Ireland and England)
  • + 1 Other Science Subject
  • Elective modules

Fourth Year

  • Geology: the year begins with a summer field-mapping research project, with follow-up research and report completion during the first semester of fourth year. There is a 10-day residential field course, usually held in Spain.

All Science courses are full time, with many student timetables running from 9.00am to 5.00pm or later. Depending on the subject choices, a weekly timetable can include lectures, practicals and tutorials.

Assessment varies with each module but may comprise continuous assessment of practicals, written exams and online learning activities.

“Geology at UCD provided me with both a solid understanding of the subject and excellent practical skills. The skills acquired through the practical coursework and field trips play an important part in my everyday work in the field of contaminated land and geotechnical ground investigation. Following my BSc degree and Master’s in Environment Engineering Technology, with UCD’s Department of Biosystems Engineering, I worked with an environmental planning consultancy in Ireland. I then relocated to the UK to work with a geo-environmental and geotechnical consultancy. I am currently enjoying living in Sydney and working with an international engineering consultancy on large-scale contaminated land remediation projects.”
