He paid especial attention to minerals connected with volcanic phenomena and igneous rocks, to the effects of metamorphism, and to mineral veins, in various parts of the world, notably in the Pyrenees. In his numerous contributions to scientific journals he dealt with the mineralogy and petrology of Madagascar, and published an elaborate and exhaustive volume on the eruptions in Martinique, ''La Montagne Pelée et ses éruptions'' (Paris 1904). He also issued an important work entitled ''Minéralogie de la France et de ses Colonies'' (1893–1898), and other works in conjunction with Auguste Michel-Lévy.
