Neue Theorie von der Entstehung der Gänge, mit Anwendung auf den Bergbau besonders den freibergischen.

xxxx, 256 pp. 8vo, cont. paste-paper boards (minor foxing), uncut. Freiberg: Gerlach, 1791.

First edition. This work by Werner, who is known as the father of historical geology, describes his "theory of the origin of ore deposits which would be consistent with his general theory of the origin of the earth's crust...Many of its elements were of lasting value. Werner formulated basic questions about the origin and history of veins and their contents, established criteria for determining the relative age of veins and vein materials, and presented a comparative study of the structure of veins and rock masses...Perhaps the most important contribution of Von den Entstehung der Gänge, however, was that it made the study of vein formation an integral part of historical geology."­D.S.B., XIV, pp. 262-63.
