Gyutton

Gyutton, speaking from his teaching at the end of the last century (1788), guided the study, called veins, filling the cracks of various layered and laminated rocks, the origin of the cracks he attributed to rupture, filling them as the rock looked like a volcanic process: in his view, in many cases, quite correctly, the molten mass poured into these slots. Thus, he considered the first origin of the basalts and the changes that occur in the rock near the veins, making the conclusion on the effects of heat. Soon he extended his theory to all the massive rocks, from granite, and argued that they represent a frozen molten mass. Schists he regarded as a layered rocks that are changed to internal heat of the earth. Thus, Gyutton is the founder of the controversial and still the doctrine of metamorphism, ie, about the changes and recrystallization of rocks that occur after their formation. In developing his views Gyutton went very far and claimed that the conventional marine sediments became only the action of the earth's heat in the limestone, sandstone, shale, etc. The formation of mountains Gyutton attributed raising the earth's crust that cause actions from below by volcanic forces. Special merit of this researcher is that he first gave a satisfactory representation of the huge gaps of time during which the committed changes the earth's surface. Works Gyuttona written obscure and difficult to clear language. This could serve as an obstacle to the dissemination of his views, if Playfair (Playfair), his friend and follower, not to present them in a clear manner and would collect many observations, confirming the views Gyuttona. Importance to this theory were the famous experiments of James Gaulle (James Hall) on the melting and solidification of rocks. Gyuttona theory as it relates to the action of internal heat of the earth and sees the massive rocks as the products of solidification of the molten mass, and finds work orogenic forces, represents a great advantage over the views of Werner. Gyutton first noticed the existence of granitic veins, and this is one of the most interesting geological observations. Finally, all those researchers who were on the point of view of plutonic metamorphism Gyuttona and did a research on changes in the rock under the influence of the internal heat of the earth, had a great service to the doctrine of metamorphism in general. The latter circumstance is not recognized by countless foes Gyuttona, however, and they agree that the scientific ideas contributed to a strong scientific stimulation. Along with the correct view, we find in Gyuttona and his followers and deep misconceptions: an exaggerated idea of ??the importance of the internal heat of the earth, even used to explain the sedimentary rock, made all the teachings of one-sided. Explains the formation of mountains through the volcanic forces is also not tenable, although it is a significant step forward compared with the theories of Werner.
