Northern Arizona University

What you'll study

The programme combines core geoscience theory, practical laboratory skills and intensive fieldwork to develop a comprehensive understanding of earth processes. Students study topics such as sedimentology and stratigraphy, structural geology and tectonics, petrology and mineralogy, geochemistry, geophysics, hydrogeology, paleontology, and Quaternary geology. Training in geographic information systems (GIS), remote sensing, geospatial analysis and numerical modelling is integrated to support modern research and applied projects.

Programme structure typically includes a mix of advanced coursework and a substantial research component. Options usually include a thesis route, centred on an independent research project supervised by faculty, and a non-thesis route, which emphasises additional coursework and a capstone project or practicum. Field courses and multi-day field trips across desert, mountain and plateau settings are a hallmark of the programme, giving hands-on experience in mapping, sampling and field-based interpretation. Laboratory work covers petrography, geochemical analysis and geochronology techniques.

Entry requirements

Applicants are normally expected to hold a bachelor’s degree in geology, earth science or a closely related field. Strong preparation in introductory geology, mineralogy, petrology, structural geology, sedimentology, and calculus or quantitative methods is typically required. A solid academic record from previous study is important.

Application materials generally include official transcripts, a statement of purpose describing research interests and career goals, and academic references. Depending on programme options and the applicant’s background, faculty may request a CV, sample of prior research or a proposed research statement. Standardised test requirements (such as the GRE) vary and should be checked with the department; international applicants must demonstrate English proficiency through recognised tests or institutional alternatives where required.

Career prospects

Graduates move into a wide range of roles across private industry, government and academia. Typical career paths include environmental and hydrogeological consulting, natural resource and mining geology, petroleum-related positions, geotechnical and engineering geology, and GIS or remote-sensing specialists. Many alumni also progress to doctoral study and research careers, or to roles in federal and state agencies (for example geological surveys, environmental protection agencies and land-management organisations), as well as work with parks and conservation bodies.

Because the programme blends field experience, analytical skills and geospatial training, graduates are equipped for work that requires site investigation, environmental permitting support, resource assessment, hazard evaluation and scientific communication.

Why study at Northern Arizona University

Northern Arizona University offers strong advantages for Earth Sciences study due to its proximity to a diversity of geological settings, including the Colorado Plateau, volcanic fields and canyon country, which provide rich field-learning environments and research opportunities. The department emphasises field-based instruction and hands-on analytical training in well-equipped laboratories.

Students benefit from close mentorship by faculty whose research covers tectonics, sedimentary systems, volcanology, paleoclimate, hydrogeology and geospatial science, and from collaboration opportunities with regional research organisations and land-management agencies. Small cohort sizes and active field courses foster practical skills, peer collaboration and direct involvement in publishable research projects. Internships and local industry connections help translate academic experience into professional pathways.
