Geology is of practical importance to mankind. It plays a very useful part in the search of coal, petroleum, minerals used as atomic fuels. It is directly concerned with the ore mineral, industrial minerals and mining industry. The importance of geology has also been recognized in the field of engineering. Many engineering projects such as water supply, construction of dams, reservoirs, tunnels, bridges, etc require geological advice.
Geology as Career:
Geology is a very vast field. Geological studies has key role in meeting the basic needs and boosting up the economies of all the countries of the world. A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes the Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field work is an important component of geology, although many subdisciplines incorporate laboratory work.
Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate change discussions.
Professional geologists work for a wide range of government agencies, private firms, and non-profit and academic institutions. They are usually hired on a contract basis or hold permanent positions within private firms or official agencies (such as the United States Geologic Survey).
Local, state, and national governments hire geologists to work on geological projects that are of interest to the public community. The investigation of a country’s natural resources is often a key role when working for government institutions; the work of the geologist in this field can be made publicly available to help the community make more informed decisions related to the exploitation of resources, management of the environment and the safety of critical infrastructure – all of which is expected to bring greater wellbeing to the country. This ‘wellbeing’ is often in the form of greater tax revenues from new or extended mining projects or through better infrastructure and/or natural disaster planning.
An engineering geologist is employed 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 use all aspects of geology and geophysics to locate and study natural resources. In many countries or U.S. states without specialized environmental remediation licensure programs, 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, and large-scale land developers use the skills of geologists and engineering geologists to help them locate oil and minerals, adapt to local features such as karst topography or earthquake risk, and comply with environmental regulations.
Geologists in academia usually hold an advanced degree in a specialized area within their geological discipline and are employed by universities.
