University of Arizona

What you'll study

The degree is built around a core of geology and earth‑science fundamentals combined with quantitative and laboratory skills. Core topics typically include mineralogy and petrology, sedimentology and stratigraphy, structural geology and tectonics, geochemistry, geophysics, paleontology, and hydrogeology. Practical training emphasises field methods and mapping, geological data collection, laboratory analysis (thin section microscopy, XRD, geochemical techniques), and geospatial methods such as GIS and remote sensing.

Programme structure normally mixes lower‑division surveys and foundational maths, chemistry and physics courses with upper‑division specialised courses and electives. Many students take a capstone or senior research project and have opportunities for independent research with faculty. Field courses in the deserts, canyons and mountain ranges of the American Southwest are a recurrent component, often including multi‑day mapping trips. Electives allow focus areas such as environmental geology, mineral resources and exploration, petroleum and energy geoscience, or planetary geology.

• Typical modules: Mineralogy, Petrology, Structural Geology, Sedimentology, Geomorphology, Geochemistry, Geophysics, Paleontology, Hydrogeology, Field Methods, GIS/Remote Sensing
• Skills developed: field mapping, rock and mineral identification, quantitative data analysis, laboratory techniques, geographic information systems, scientific communication
• Assessment: laboratory reports, field maps and notebooks, written exams, research projects and oral presentations

Entry requirements

Applicants are expected to have a strong foundation in mathematics and the natural sciences from high school. Recommended preparation includes courses in calculus (or precalculus), chemistry and physics; an introductory earth science course is helpful but not always required. Admissions decisions consider overall academic record, relevant coursework, personal statement and extracurricular engagement such as field clubs or science research.

For international applicants, equivalent secondary credentials (for example IB or national school leaving qualifications) with preparation in maths and sciences are required. Transfer students from community colleges or other universities typically need completion of introductory calculus and science sequences; specific credit transfer is assessed on an individual basis. Standardised tests are considered according to the University of Arizona's current admissions policy.

Career prospects

Graduates enter a broad range of careers across natural resource industries, environmental management and government and research organisations. Common pathways include:

• Environmental and engineering consulting (site assessment, remediation, geohazard evaluation)
• Mineral exploration and mining geoscience
• Hydrogeology and water‑resource management
• Petroleum and energy sector roles (often combined with postgraduate training)
• Geotechnical and civil engineering support (with additional professional qualifications)
• Government and regulatory agencies (for example geological surveys and environmental protection agencies)
• Academic and laboratory research, and science communication or education

The degree also provides strong technical and analytical skills valued in GIS and geospatial analysis, data science roles, and related tech sectors. Undergraduate research, internships and field experience often improve employability and can lead directly to positions with industry partners and government bodies.

Why study at University of Arizona

The University of Arizona is well suited to earth‑science students because of its location in a geologically diverse region and its strong tradition of field‑based training and research. Students benefit from long established field courses across the deserts, mountain ranges and Grand Canyon region, access to modern laboratories and instrumentation, and opportunities to work within active research groups in geochemistry, geophysics, stratigraphy and planetary science.

The university hosts facilities and initiatives that complement earth‑science training, including major GIS and remote sensing resources, Biosphere 2 for environmental and climate research, and established partnerships with regional industry, national laboratories and federal agencies. Career services, research assistantships and internship networks help connect students with employers in mining, environmental consulting, water resources and government bodies, supporting a practical transition from study to professional work.
