A 'geologist' is a contributor to the
science of
geology, studying the physical structure and processes of the
Earth and planets of the solar system (see
planetary geology).
Training / Schooling
Their undergraduate training typically includes significant coursework in
physics,
mathematics and possibly
biology, in addition to classes offered through the geology department;
volcanology,
hydrology, and
rock and
mineral formation are among the many areas of study. Most geologists also need skills in
GIS and other
mapping techniques. Geology students may spend summers living and working under field conditions with faculty members. Geology courses are also highly valuable to students of
geography,
engineering, chemistry,
urban planning,
environmental studies, and other fields.
Areas of specialization
Geologists may concentrate their studies or research in one or more of the following disciplines:
★
Economic geology: the study of
ore genesis, and the mechanisms of ore creation,
geostatistics.
★
Geochemistry: the study of the chemical makeup and behaviour of rocks, and the study of the behaviour of their minerals.
★
Geochronology: the study of isotope geology specifically toward determining the date within the past of rock formation,
metamorphism, mineralization and geological events (notably,
meteorite impacts).
★
Hydrogeology: the study of the origin, occurrence and movement of water in a subsurface system, primarily
groundwater.
★ Igneous petrology: the study of igneous processes such as
igneous differentiation,
fractional crystallization, intrusive and volcanological phenomena .
★
Isotope geology: the study of the isotopic composition of rocks to determine the processes of rock and planetary formation.
★ Metamorphic petrology: the study of the effects of
metamorphism on minerals and rocks.
★
Marine geology: the study of the seafloor; involves geophysical, geochemical, sedimentological and paleontological investigations of the ocean floor and coastal margins. Marine geology has strong ties to physical oceanography and plate tectonics.
★
Palaeoclimatology: the application of geological science to determine the climatic conditions present in the Earth's atmosphere within the Earth's history.
★
Palaeontology: the classification and taxonomy of fossils within the geological record and the construction of a palaeontological history of the Earth.
★
Pedology: the study of soil, soil formation, and
regolith formation.
★
Petroleum geology: the study of
sedimentary basins applied to the search for
hydrocarbons (
oil exploration).
★
Sedimentology: the study of
sedimentary rocks,
strata, formations,
eustasy and the processes of modern day sedimentary and erosive systems.
★
Structural geology: the study of
fold (geology),
geological fault,
foliation (geology) and
rock microstructure to determine the and deformational history of rocks and regions.
★
Volcanology: the study of
volcanoes, their eruptions,
lavas,
magma processes and hazards.
Employment opportunities
Professional geologists work for a wide range of government agencies, private firms, and non-profit and academic institutions. Local, state, and national governments hire geologists to help plan and evaluate excavations, construction sites, environmental remediation projects, and natural disaster preparedness, as well as to investigate natural resources. An
engineering geologist (a geologist trained, experienced and certified in the field of
engineering geology) is called upon to investigate
geologic hazards and geologic constraints for the planning, design and construction of public and private engineering projects,
forensic and post-mortem studies, and
environmental impact analysis. Exploration geologists utilize all aspects of geology and geophysics to locate and study natural resources. In many countries or US states without specialized environmental remediation licensure programs, such as Rhode Island and North Carolina, the environmental remediation field is often dominated by professional geologists, particularly hydrogeologists, with professional concentrations in this aspect of the field.
Petroleum and
mining companies use
mudloggers (or wellsite geologists) and large-scale land developers use geologists' and
engineering geologists' skills to help them locate oil and minerals, adapt to local features such as
karst deposits or the risk of
earthquakes, and comply with environmental regulations. Geologists in academia usually hold an advanced degree in a specialized area within the discipline.
