RENARD, See also:ALPHONSE See also:FRANCOIS (1842-1903) , Belgian geologist and petrographer, was See also:born at See also:Renaix, in Eastern See also:Flanders, on the 27th of See also:September 1842. He was educated for the See also:church of See also:Rome, and from 1866 to 1869 he was See also:superintendent at the See also:College de la Paix, See also:Namur. In 1870 he entered the Jesuit Training College at the old See also:abbey of Maria Laach in the See also:Eifel, and there, while engaged in studying See also:philosophy and See also:science, he became interested in the See also:geology of the See also:district, and especially in the volcanic rocks. Thenceforth he worked at See also:chemistry and See also:mineralogy, and qualified himself for those petrographical researches for which he was distinguished. In 1874 he became See also:professor of chemistry and geology in the college of the Belgian See also:Jesuits at See also:Louvain, a few years later he was appointed one of the curators of the Royal Natural See also:History Museum at See also:Brussels, and in 1882 he relinquished his See also:post at Louvain. In 1888 he was chosen professor of geology at the university of See also:Ghent, and retained the post until the See also:close of his See also:life. Meanwhile he had been ordained See also:priest in 1877, and had intended to enter the Society of Jesus. He was known as the See also:Abbe Renard; but, as remarked by See also:Sir A. See also:Geikie, " As years passed, the longing for See also:mental freedom See also:grew ever stronger, until at last it overmastered all the traditions and associations of a lifetime, and he finally separated himself from the church of Rome." His first See also:work, written in See also:conjunction with See also:Charles de la Vallee-Poussin (1827-1904), was the Memoire sur See also:les caracteres mineralogiques et stratigraphiques See also:des roches dices plutoniennes de la Belgique et de l'Ardenne francaise (1876). In later essays and papers he dealt with the structure and See also:mineral See also:composition of many igneous and sedimentary rocks, and with the phenomena of See also:metamorphism in See also:Belgium and other countries. In See also:acknowledgment of his work the See also:Bigsby See also:Medal was in 1885 awarded to him by the See also:Geological Society of See also:London. Still more important were his later researches connected with the Challenger Expedition.

The various See also:

rock specimens and oceanic deposits were submitted to him for examination in association with Sir See also:John See also:Murray, and their detailed observations were embodied in the See also:Report on the Scientific Results of the Voyage of H.M.S. " Challenger." Deep See also:Sea Deposits (1891). The more striking additions to our knowledge included " the detection and description of See also:cosmic dust, which as See also:fine See also:rain slowly accumulates on the ocean See also:floor; the development of zeolitic crystals on the sea-bottom at temperatures of 32° and under; and the See also:distribution and mode of occurrence of manganiferous concretions and of phosphatic and See also:glauconite deposits on the See also:bed of the ocean " (Geikie). Renard died at Brussels on the 9th of See also:July 1903. Obituaries by Sir A. Geikie in Quart. Journ. Geol. See also:Soc., 1x. 1904, and in Geol. Mag., Nov. 1903.
