Life

Born in Quebec City Logan studied at the University of Edinburgh. When he took over in 1831 to operate a mine in South Wales at Swansea, he began to dwell on geology. He made a geological map of the coal fields of South Wales. Based on the points made on this research, he wrote the article "On the nature of the clay soils, which are located immediately below the coal seams of South Wales and the present on the site carbon inclusions in the sandstone ," which he in 1840 at the Geological Society of London submitted. In this document, Logan expressed the belief that it was in the layer below the coal fields around the old surface on which the plants from their remains, the coal had formed, were once grown.

Logan's geological skills soon found recognition and 1842 he was commissioned to analyze the Geological Survey of Canada to establish whose director he remained until 1869. During his time as director, he described the Laurentian rock formations in the Canadian Laurentian Mountains and the Adirondack Mountains in upstate New York.

Among other things, he was in 1855 by the French emperor Napoleon III. received the Legion of Honour in 1856 and charged by the British Queen Victoria to knighthood. In the same year, Logan received the Wollaston Medal of the Geological Society of London.

Retired Logan in 1869 moved back to Pembrokeshire in West Wales, where he died in 1875. He was buried in a cemetery in Cilgerran.
