The Department of Geology has started its journey in 2017 with recruitment of two Assistant Professors and enrolment of 18 (eighteen) students to B.Sc. (Hons.) course from the session 2017-18 with Prof. Nishamani Kar, Dean of the Faculty of Environmental Sciences as its Co-ordinator. Being located in the foothills of eastern part of the Himalaya, the department has a brighter vision to engage the students in academic and research activities to better understand various aspects of geology of the eastern Himalaya and of the NE India.

Arunachal Pradesh is the largest state in NE India with availability of natural laboratory for geoscientists in the form of rock exposures to unravel the surface and subsurface geological processes. Large part of the state is still geologically unexplored while the state has a large potential for natural resources in term of mineral wealth, coal, hydrocarbon etc. besides huge potential for hydropower. Since the state lacks any institution offering higher education in Geosciences, even at undergraduate level, this department was established as a consequence to the recommendation and suggestion made by Prof. O. P. Varma (Executive President of Indian Geological Congress) and others during the 19^th convention of ‘Indian Geological Congress’ held in November, 2014 in Rajiv Gandhi University.

Initially the department has started offering three year undergraduate course (B.Sc.) with honours in Geology but subsequently postgraduate and research courses will also be introduced in due course of time. The curriculum for the undergraduate course is designed in such a way to lay strong foundation in theoretical, practical and field knowledge for the students. Besides, the department is also committed to play a pivotal role for high quality research in different geo-scientific aspects of Eastern Himalaya.
