No, based on the eligibility criteria, you wouldn't be eligible to apply for the IIT JAM program in Geology with a graduation degree in Geography from the University of Calcutta.

The minimum qualification for the JAM Geology (GG) program typically requires a Bachelor's degree in Geology or a related field for three years/six semesters. While Geography is a related field in terms of studying the Earth, it focuses more on human-environment interactions and social aspects, differing from the focus of Geology on the Earth's physical structure and processes.

The JAM Geology program delves into subjects like Petrology, Mineralogy, Paleontology, which require a strong foundation in the core principles of Geology. A Geography degree might not have covered these specific areas in sufficient depth

Several universities offer Master's programs in Geography with specializations like Environmental Geography, Resource Management, etc. These programs might be a good fit considering your background. Some universities offer integrated M.Sc. programs in Geology or Earth Sciences. These five-year programs are designed for students who haven't studied Geology at the undergraduate level.
