University of Arizona

What you'll study

The programme combines advanced coursework, original research and hands-on field and laboratory training. Students typically follow a thesis-based Master’s route, although some options for professional or coursework-focused pathways may be available through allied units. Core areas of study include:

• Field methods and structural geology: detailed mapping, strain analysis and tectonic interpretation using regional exposures in the American Southwest.
• Petrology and mineralogy: laboratory-based study of igneous, metamorphic and sedimentary rocks, including thin-section petrography and mineral chemistry.
• Geochemistry and isotope systems: element mobility, radiogenic and stable isotopes for dating, provenance and paleoenvironmental reconstruction.
• Geophysics and remote sensing: seismic interpretation, gravity/magnetic methods, potential-field data, and application of remote sensing and LiDAR for surface processes.
• Sedimentology and basin analysis: depositional systems, stratigraphy and basin evolution, including petroleum and sediment-hosted mineral systems.
• Hydrogeology and environmental geology: groundwater flow, contaminant transport, remediation strategies and applied site characterisation.
• Computational and quantitative skills: GIS, sediment transport modelling, numerical geodynamics and data analysis using scientific programming and statistics.

Students undertake a research project under faculty supervision that culminates in a written thesis and oral defence. Regular departmental seminars, journal clubs and opportunities for multi-disciplinary collaboration are integral to the programme. Extensive field trips and access to on-campus laboratories give practical experience in sample preparation, geochemical instrumentation (e.g. mass spectrometry), and rock and sediment analyses.

Entry requirements

Applicants normally hold a bachelor’s degree in geology, earth sciences or a closely related physical science or engineering discipline. Typical academic expectations include a solid foundation in mathematics, physics, chemistry and core geoscience subjects (e.g. mineralogy, petrology, structural geology, sedimentology).

• Academic transcript: official transcripts demonstrating strong academic performance in undergraduate coursework.
• Statement of purpose: a clear description of research interests, relevant experience and career objectives.
• Letters of recommendation: usually two or three letters from academic or professional referees familiar with the applicant’s preparedness for graduate study.
• Curriculum vitae / résumé: outlining research, fieldwork, internships or relevant employment.
• English language proficiency: for applicants whose first language is not English, an approved English test or equivalent evidence of proficiency is required.

Applicants with gaps in specific undergraduate preparation may be admitted with conditional requirements (for example, completion of certain undergraduate courses). Prospective students are encouraged to contact potential faculty supervisors to discuss research alignment before applying.

Career prospects

Graduates move into a broad range of careers across industry, government and academia. Common roles include:

• Environmental and hydrogeological consultant working on groundwater resources, contaminated-site assessment and remediation.
• Exploration and mining geologist involved in resource characterisation and mine planning.
• Petroleum, geothermal and energy sector geoscientist focusing on subsurface characterisation and reservoir evaluation.
• Geotechnical and engineering geology roles supporting infrastructure, hazard assessment and site investigation.
• Geoscience specialist in government agencies, geological surveys and natural-hazard organisations.
• Academic or research scientist pursuing PhD study, university teaching or postdoctoral research.
• GIS and remote sensing analyst applying spatial techniques to natural-resource management and environmental monitoring.

Students benefit from the department’s links with regional industry, government laboratories and professional networks, which support internships and employment opportunities.
