In his many contributions to scientific journals he described thegranulite group, and dealt withpegmatite s,variolite s,eurite s, theophite s of thePyrenees , the extinctvolcano es of Central France,gneiss es, and the origin of crystallineschist s.He wrote "Structures et classification des roches éruptives" (1889), but his more elaborate studies were carried on with F Fouqué.
