Bücher der Reihe Traite de Geognosie 2 Volume Set

Published in 1819, Aubuisson de Voisins' two-volume Traite de Geognosie was one of the earliest geology books in French. It convincingly challenged the 'Neptunist' theory of his influential teacher Gottlob Werner, arguing that the basaltic rocks and mineral veins of the earth's crust were of igneous, not marine, origin.
