Geologist conducts research into the nature and history of the Earth’s crust to increase scientific knowledge and to develop practical applications in such fields as mineral exploitation and civil engineering. He/she applies theoretical knowledge and research data to locate and assess the development potential of mineral, gas, and oil deposits and underground water resources, and applies geological knowledge to problems encountered in civil engineering projects such as construction of dams, bridges, tunnels and large buildings. He/she prepares geological maps and diagrams of regions studied, using aerial photographs where available.

Main tasks

• Conducting research and improving or developing concepts, theories and operational methods related to geology and geophysics
• Studying composition and structure of the Earth’s crust, examining rocks, minerals, fossils and other materials, to determine processes affecting the development of the Earth, trace evolution of past life, establish nature and chronology of geological formations and assess their commercial applications
• Interpreting research data and preparing geological reports, maps, charts and diagrams, reports and papers
• Using various remote sensing programmes to investigate and measure seismic, gravitational, electrical, thermal, and magnetic forces affecting the Earth
• Estimating weight, size and mass of the Earth and composition and structure of its interior, and studying the nature, activity and predictability of volcanoes, glaciers and earthquakes
• Locating and determining the nature and extent of oil, gas and mineral deposits using seismological, gravimetric, magnetic, electrical or radiometric methods
