What is Geology?

Geology is the study of the earth, its processes, its materials, its life, and how these have changed over 4.567 billion years of time. Information gathered by geoscientists helps us understand the changing climate, predict earthquakes and volcanic eruptions, find supplies of fossil fuels and mineral ores, maintain clean air and water, understand the motion of the earth’s crust and oceans, and reconstruct the evolution of the rocky planets and life.

Is this the right course for you?

If you like science, care about the earth, are fascinated by the natural world and enjoy working outdoors, then consider Geology. Geology attracts people who wish to study the dynamics of the Earth we live on, its resources, and the most economic and sustainable way to use these resources.

Why study Geology at Trinity?

At Trinity, our staff investigate the fundamental principles of geological processes, which occur at a vast range of spatial and temporal scales. We combine fieldwork in Ireland, across Europe and around the world, with laboratory analyses, numerical modelling and theory. Students participate in this cutting-edge research whilst developing keen observational and analytical skills taught both in the field and the laboratory. Our graduates apply these skills to a wide range of geoscientific questions, aimed at understanding Earth’s history and its future, and the sustainability of energy and resources required to support a growing human population.

What will you study?

In the third (Junior Sophister) year, a thorough grounding is provided in all major branches of geology. In the Senior Sophister (fourth) year you will take a series of compulsory courses, but also four optional subjects from a wide range covering both academic and applied areas of geology. In your Sophister years you will also have the opportunity to undertake several field trips to geologically active areas such as Greece and Spain.

Study abroad

Further information on the year abroad programme, and a list of partner universities, can be found by emailing our International Student co-ordinator, Quentin Crowley:


Geology is a highly interactive, interdisciplinary and rewarding subject. Geology addresses critical issues such as energy, meteorology, water and mineral resources, stewardship of the environment, oceanography, reducing natural hazards for society, planetary science and more. Not only does this major allow students to work on many of society’s most important challenges, but it also unlocks lucrative and personally rewarding careers in industry, academia, research and government.

Recent graduates have found professional career opportunities with mineral exploration companies, civil engineering firms, geological and environmental consultancies, oil companies, organisations based in computing and information systems, and government geological surveys. There is currently a global shortage of geoscientists. Geology graduates are also highly valued in more generalised fields of employment due to their adaptability, their many transferable skills and their experience at dealing with incomplete data sets.

Graduate Profile

Dr Catherine Duggan

For me, Geology was one of the best kept secrets ever. I chose it as one of my first year subjects in the Science degree without knowing much about it. Geology combines elements of physics, chemistry and biology, and changes the way you look at the world around you. An integral part of the course were the field trips – they were hard work, out all day (in not always the best weather) but the social element was brilliant. Because of them you get to know the whole department – students, postgrads and staff, making it much better than a purely lecture-based course.
