Erste Ausgabe. - "His 'Lehrbuch der Geognosie' was the most authoritative work on petrography in the mid-nineteenth century and served as a standard textbook for decades... In it he differentiated rocks primarily according to their origin, which he determined from their texture, for example, crystalline, clastic, and hyaline. He supported the theory that most gneisses and schists had been formed from sedimentary rocks but admitted that some gneisses had been produced by the deformation of igneous rocks. The first text to devote considerable space to tectonics, his 'Lehrbuch' contained all of the scientific information known about earthquakes at that time. Naumann held that certain earthquakes occurred independently of any volcanic activity and might therefore be termed "plutonic". This view was in opposition to that of Humboldt, who believed earthquakes and volcanoes to be merely different manifestations of the same causes" (DSB). - Naumann (1797-1873), Schüler von A. G. Werner, war Professor für Kristallografie und Geognosie an der Bergakademie in Freiberg und ab 1842 für Mineralogie und Geognosie an der Universität in Leipzig. - Gestempelt (Tafeln verso). Stellenweise leicht stockfleckig, sonst gut erhalten. - DSB 9, 620; Poggendorff II, 257
