hi,

see geological technology course syllabus is more technical oriented and it has wide coverage of technical domain applied in geological science. however coming to the institute placement and opportunity IIT kharapur comes ahead since it rank is under top five iits of India. also placement, research and lab structures is far better in IIT kharagpur. so in that point of view I would prefer to put iit kharagpur msc geology course ahead.

hope it would help.
