Alexander von Humboldt. Elie de Beaumont

As already mentioned, Leopold r. Buch shows that the location of mountains in Germany can be noted four main areas. Following this, the famous geologist Elie de Beaumont created the theory of mountain building, which has long drawn global attention to themselves. Elie de Beaumont, the main merit of which is the geological map of France, developed in conjunction with Dufresnoy, develop further ideas Buha, in some cases his conclusions are very valuable, in others - are wrong. Like his German predecessor, he tried, as far as the facts to determine the direction of mountain systems throughout the land. Pursuing this question, Elie de Beaumont has gained a lot of factual material and caught a lot of new laws, he first, and not without success, tried to determine the time during which the mountains were formed. The method used for that purpose, clear and simple: is determined by the age of the uppermost strata of those who participated in the formation of mountains. Then determined by the age of the oldest of the sediments, which lie at the bottom without breaking the accuracy of their reservoir, obviously, the mountain popped up during the time that elapsed between the formation of both breeds. The introduction of this completely correct method had a great service to science. But already the first conclusion of Elie de Beaumont, was not quite true: there is no reason to assume that the formation of mountains occurs in one step. Using this method it, we can not determine the time within which the process occurred, but only defines the beginning and end of the latter. On this pin Elie de Beaumont has built a number of other theories that were even more flawed. According to him, all the parallel mountain ranges were formed at the same time, he even admitted that their directions are correct to the extent that the edges of the crystals. Imagining every mountainous region due to a sudden uplift the crust, Elie de Beaumont had seen during their education those catastrophes, which, in theory, Cuvier, periodically destroying flora and fauna. This hypothesis has long enjoyed great attention, especially in France, but now finally rejected.
