Jules Levallois

from Wikipedia, the free encyclopedia

Joseph Jean Baptiste Jules Levallois (* 1799 ; † 1877 ) was a French geologist and mining engineer.

Levallois studied from 1816 at de École Polytechnique and then at the École des Mines . Then he was in the Corps des Mines and was involved in the development of salt deposits in Lorraine. From 1821 to 1825 he headed the Vic-sur-Seille salt mine and then that of Dieuze, which he remained even after it was privatized. In 1834 he published in the Annales des Mines on salt exploration in the Meurthe department. He also contributed to the study of the geology of Lorraine in general. Most recently he was inspector general for mining in France.

In his honor is the dedication name of the Ceratiten Ceratites levalloisi (BENECKE 1914) by Ernst Wilhelm Benecke . A slate formation in the upper Keuper in Lorraine is named after him ( Argiles de Levallois ).

In 1860 he was president of the Société géologique de France . With Charles Édouard Thirria (1796-1868) and Ours-Pierre-Armand Petit-Dufrenoy (1792-1857) he was in a commission that prepared the legislation for mineral springs in France.

Between 1842 and 1868 he was involved in a debate with the pioneer of paleontologically oriented stratigraphy in France, Olry Terquem, about the stratigraphic classification (Jura (Lias) or Trias (Rhät)) of the hettangium . Terquem's view finally prevailed.
