"With the scarce atlas. The first comprehensive book on Canadian geology. The work received national and international acclaim for its content, style, and precision and is still considered to be one of the most important Canadian scientific works of nineteenth century Canada". Logan, Sir William Edmond, geologist, first director of the Geological Survey of Canada (b. at Montréal 20 Apr 1798; d. at Castle Malgwyn, Cilgerran, S Wales 22 June 1875). Logan identified and mapped the major geological structures of the Province of Canada, in particular the Laurentian and Huronian series of the Precambrian Shield Logan's reputation as a geologist, his Canadian birth, and his social and family connections in Montréal secured him the position of geologist of the Province of Canada in Apr. 1842. By 1844 Logan and one assistant, Alexander MURRAY, had divided the geological formations of the province into 3 main divisions. Logan became the first native Canadian inducted into the Royal Society of London for achievements in Canada. A knighthood followed in 1856. While the Survey continued investigations in both laboratory and field. Logan in 1863 published Geology of Canada, followed in 1865 by an atlas and in 1869 by a larger geological map. This masterly analysis of Canada's geological structures and economic minerals earned Logan the Royal Soc's Gold Medal in 1867.

Libris: Séminaire de Philosophie Montréal on free endpaper.Sir William Edmond Logan was a major contributor to the Geological Survey of Canada. Logan stated: ?The object of the Survey is to ascertain the mineral resources of the country,? and the survey still operates on this principle. Subsequent to 1855 he saw the development of a major copper-producing area in the Eastern Townships, where the Acton Mine was said to be the largest copper mine in the world in its time. The Geological Survey?s greatest contribution during Logan?s tenure as director was producing reports and maps, which established the fundamentals of Canadian geology; especially important were those for the north shore of Lake Huron and Lake Superior where rich beds of copper, nickel, uranium, iron, platinum, and other metals occur in the ancient rocks of the Precambrian?
