Thèse de doctorat : Université de Neuchâtel, 2007 ; Th.1975.

Being an extremely heterogeneous medium, electric resistivity of volcanic rocks extends over a large range. This physical property is strongly related to the minerals that form these rocks, to the electrical conductivity of fluids that may soak through the rocks, or to the bulk porosity. The spatial distribution of this property allows to infer internal structures of a volcanic edifice and to...
