Buch, Christian Leopold, Freiherr von
Christian Leopold Buch, Freiherr von (krĬs´tyän lā´ōpôlt frī´hĕr fən bōōkh), 1774–1853, German geologist and paleontologist, graduate of the mining academy, Freiberg, Germany, and taught by geologist Abraham G. Werner, who founded the influential Neptunist School (rocks from aqueous origins). Buch's later studies of Mt. Vesuvius found flaws in Werner's hypothesis. Buch is noted for his study of volcanism in the Canary Islands and British Isles. He developed the first geological map of Germany and was the first to determine that granites were formed by igneous processes and that the Alps resulted from an upheaval in the earth's crust.
