More information

Delesse was born at Metz. At the age of twenty he entered the École Polytechnique, and subsequently passed through the Ecole des Mines. In 1845, he was appointed to the chair of mineralogy and geology at Besançon; in 1850, to the chair of geology at the Sorbonne in Paris; and in 1864, professor of agriculture at the Ecole des Mines. In 1878, he became inspector-general of mines.



In early years as ingénieur des mines he investigated and described various new minerals; he proceeded afterward to the study of rocks, devising new methods for their determination, and giving particular descriptions of melaphyre, arkose, porphyry, syenite, and others. The igneous rocks of the Vosges, and those of the Alps, Corsica, etc., and the subject of metamorphism occupied his attention. He also prepared in 1858 geological and hydrological maps of Paris, with reference to the underground water, similar maps of the départements of the Seine and Seine-et-Marne, and an agronomic map of the Seine-et-Marne (1880), in which he showed the relation that exists between the physical and chemical characters of the soil and the geological structure.
