Vue d'ensemble de l'équipe chargée d'étudier la conductivité électrique du manteau supérieur par sondage magnétotellurique profond sous le massif volcanique du Hoggar, situé dans le Sahara algérien. De telles recherches devraient permettre de préciser l'histoire du soulèvement du Hoggar ainsi que la nature des processus qui en sont à l'origine.
