Department of Geology


The Department of Geology is located in the geomorphology formation of Nagapattinam and established in 2017. The department offers three years B.Sc Geology from 2017 onwards. It is one of the pioneering departments which were trifurcated from erstwhile School of Earth Sciences. It does move towards to attain to the level of department of advanced studies in Geology. In addition, the department organizes seminars, workshop, and conferences in National and International level. The fundamental objective of this programme to builtayoung charming women for professional careers in the field of Geology by providing a broad education in all aspects of the geoscience and equip the students with appropriate knowledge and skills to make them employable and capable to serve the nation. The Department of Geology strives to design and develop scientific tools to explore, exploit and manage Georesources such as water, rock, minerals and soil. The students of the department are sent to reputed organizations for the summer training. Apart from the regular lecture frequent field visits have been conducting to improve the practical knowledge of the students.


  • Geology is a branch of Earth Science concerned with both the liquid and solid earth the rocks of which it is composed and the processes by which they change over time.
  • Geology can also include the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon.
  • Modern geology significantly overlaps all other Earth sciences, including hydrology and the atmospheric sciences, and so is treated as one major aspect of integrated Earth system science and planetary science.
  • Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure.
  • It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.
  • By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth.
  • Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates.                            
  • Geologists use a wide variety of methods to understand the Earth's structure and evolution, including field work, rock description, geophysical techniques, chemical analysis, physical experiments, and numerical modelling.
  • In practical terms, geology is important for mineral and hydrocarbon exploration and exploitation, evaluating water resources, understanding of natural hazards, the remediation of environmental problems, and providing insights into past climate change.
  • Geology is a major academic discipline, and it is central to geological engineering and plays an important role in geotechnical engineering.



       To become a centre of excellence both in teaching. The provide high quality enthusiastic earth science graduates to the nation to build a geological museum since it is very precious store of fossils and minerals. To builta good research to serve the nation.


The mission of the Department of Geology is to provide high-quality undergraduate education, to achieve excellence in research, and to interact with society and the State by translating the implications of research through outreach and service, for the benefit of the nation and humankind.
