Tasks for Geoscientists, Except Hydrologists and Geographers
- Studies, examines, measures, and classifies composition, structure, and history of earth's crust, including rocks, minerals, fossils, soil, and ocean floor.
- Locates and estimates probable gas and oil deposits, using aerial photographs, charts, and research and survey results.
- Interprets research data, and recommends further study or action.
- Tests industrial diamonds and abrasives, soil, or rocks to determine geological characteristics, using optical, x-ray, heat, acid, and precision instruments.
- Analyzes engineering problems at construction projects, such as dams, tunnels, and large buildings, applying geological knowledge.
- Develops instruments for geological work, such as diamond tool and dies, jeweled bearings, and grinding laps and wheels.
- Recommends and prepares reports on foundation design, acquisition, retention, or release of property leases, or areas of further research.
- Measures characteristics of earth, using seismograph, gravimeter, torsion balance, magnetometer, pendulum devices, and electrical resistivity apparatus.
- Inspects proposed construction site and sets up test equipment and drilling machinery.
- Prepares geological reports, maps, charts, and diagrams.
- Identifies and determines sequence of processes affecting development of earth.
