In 1835 he was appointed professor of geology at the École des Mines, in succession to Brochant de Villiers, whose assistant he had been in the duties of the chair since 1827. He held the office of engineer-in-chief of mines in France from 1833 until 1847, when he was appointed inspector-general; and in 1861 he became vice-president of the Conseil-General des Mines and a grand officer of the

An elaborate statement and criticism of the theory was given in his anniversary address to the

. It is 3109m high. Probably the best service Élie de Beaumont rendered to science, however, was in connection with the geological map of France, in the preparation of which he had the leading share. During this period Élie de Beaumont published many important memoirs on the geology of the country. After his retirement from the École des Mines he continued to superintend the issue of the detailed maps almost until his death, which occurred at Canon. His academic lectures for 1843-1844 were published in 2 volumes, (1845–1849), under the title ''Leçons de Géologie pratique''.
