He also carried out many field investigations on economic mineral deposits of the former Madras Presidency. Furthermore, Krishnan investigated radioactive minerals and rare-earth minerals, which were to form the nucleus of the atomic minerals division of the Department of Atomic Energy. He authored Textbook on Geology of India and Burma, which is currently in its sixth edition.

Other Contributions: Krishnan played a key role in the nationalization of metallurgical coal in India. The UN report (1954) on the global ore resources had incorporated several important suggestions he had made.
