.
In 1790-1793 he studied at the See also:mining school of See also:Freiberg under See also:Werner, one of his See also:fellow-students there being See also:Alexander von See also:Humboldt
.
He afterwards completed his See also:education at the See also:universities of See also:Halle and See also:Gottingen
.
His Versuch einer mineralogischen Beschreibung von See also:Landeck (See also:Breslau, 1797) was translated into See also:French (See also:Paris, 18o5), and into See also:English as See also:Attempt at a Mineralogical Description of Landeck (See also:Edinburgh, 181o); he also published in 1802 Entwurf einer geognostischen Beschreibung von Schlesien (Geognostische Beobachtungen auf Reisen durch Deutschland and Italien, See also:Band i.)

.
In 1747 he met Humboldt at See also:Salzburg, and with him explored the See also:geological formations of See also:Styria, and the adjoining See also:Alps
.
In the See also:spring of the following See also:year, von See also:Buch extended his excursions into See also:Italy, where his faith in the Neptunian theory was shaken
.
In his previous See also:works he had advocated the aqueous origin of basaltic and other formations
.
In 1799 he paid his first visit to See also:Vesuvius, and again in 18o5 he returned to study the See also:volcano, accompanied by Humboldt and See also:Gay Lussac
.
They had the See also:good See also:fortune to See also:witness a remarkable eruption, which supplied von Buch with data for refuting many erroneous ideas then entertained regarding volcanoes
.
In 1802 he had explored the See also:extinct volcanoes of See also:Auvergne
.
The aspect of the See also:Puy de See also:Dome, with its See also:cone of See also:trachyte and its strata of basaltic See also:lava, induced him to abandon as untenable the doctrines of Werner on the formation of these rocks
.
The scientific results of his investigations he embodied in his Geognostische Beobachtungen auf Reisen durch Deutschland and Italien (See also:Berlin, 1802-1809)

Buch repaired to the See also:north, and spent two years among the Scandinavian islands, making many important observations on the See also:geography of See also:plants, on climatology and on See also:geology
.
He showed that many of the erratic blocks on the North German plains must have come from Scandinavia
.
He also established the fact that the whole of See also:Sweden is slowly but continuously rising above the level of the See also:sea from Frederikshald to See also:Abo

Smith, the See also:Norwegian botanist
.
His observations here convinced him that these and other islands of the See also:Atlantic owed their existence to volcanic See also:action of the most intense See also:kind, and that the See also:groups of islands in the South Sea are the remains of a pre-existing See also:continent
.
The See also:physical description of the Canary Islands was published at Berlin in 1825, and this See also:work alone is regarded as an enduring See also:monument of his labours
.
After leaving the Canaries von Buch proceeded to the See also:Hebrides and the coasts of See also:Scotland and See also:Ireland
.
Palaeontology also claimed his See also:attention, and he described in 1831 and later years a number of Cephalopods, Brachiopods and Cystidea, and pointed out their stratigraphical importance
.
In addition to the works already mentioned von Buch published in 1832 the magnificent Geological See also:Map of See also:Germany (42 sheets, Berlin)
.
His geological excursions were continued without interruption till his 78th year
.
Eight months before his See also:death he visited
the mountains of Auvergne; and on returning See also:home he read a See also:paper on the See also:Jurassic formation before the See also:Academy of Berlin

Under this See also:guise, the passer-by would not easily have recognized the See also:man whom Humboldt pronounced the greatest geologist of his time
