Published a geological map and accompanying description of the district of Strath in April 1857 (On the Geology of Strath, Skye; Quarterly Journal of the Geological Society (of London), Volume 14). As the director of the Geological Survey of Scotland, published a paper in 1871 on the lava plateau of the British Isles, suggesting a Tertiary age (On the Tertiary Volcanic Rocks of the British Isles; Quarterly Journal of the Geological Society, Volume 27, 279-311). As director-General of the British Geological Survey, published an important memoir History of volcanic action during the Tertiary Period in the British Isles (Transactions of the Royal Society of Edinburgh, Volume 35). In 1880s, oversaw the geological mapping of the Moine Thrust Belt/Zone along the west coast of NW Scotland, extending south onto the Isle of Skye, ultimately published in 1907 as the classic British Geological Survey memoir, The Geological Structure of the North-West Highlands of Scotland (Peach, B.N., Horne, J., Gunn, W., Clough, C.T. & Hinxman, L.W.), and, in 1910, the associated memoir The Geology of Glenelg, Lochalsh and south-east part of Skye (Peach, B.N., Horne, J., Woodward, H.B., Clough, C.T., Harker, A. & Wedd, C.B.), the latter a more detailed account of the Moine Thrust Belt/Zone in SE Skye.
An academic based in the Royal School of Mines (now part of Imperial College, London) published key papers on the ‘secondary’ rocks of Scotland: (i) The Secondary Rocks of Scotland; (Quarterly Journal of the Geological Society, Volume 29 in 1873); (ii) The Secondary Rocks of Scotland. Second Paper. On the Ancient Volcanoes of the Highlands and the Relations of their Products to the Mesozoic Strata (Quarterly Journal of the Geological Society, Volume 30 in 1874); and, (iii) The Secondary Rocks of Scotland. Third Paper. The Strata of the Western Coast and Islands (Quarterly Journal of the Geological Society, Volume 34 in 1878).
An academic with a life-long career in the University of Cambridge, who was seconded to the British Geological Survey on a part-time basis (Summer to undertake fieldwork) at the request of Archibald Geikie, then director-general of the Survey. In one of his archived diaries (8th May 1895) he notes ‘I become (a) member of the Geological Survey of Scotland’: at first as Assistant Geologist, subsequently (in 1901) as Geologist (until ‘retirement’ in 1905: positions, perhaps, not fully signifying his international eminence in igneous petrology, recognized more fully by his fellowship of the Royal Society and many national and international awards and medals). His monumental work on Skye resulted in the classic memoir The Tertiary Igneous Rocks of Skye published in 1904, together with large contributions to the British Geological Survey maps of Central Skye (Sheet 70 (Minginish, published in 1904, with a small contribution by C.T. Clough)) and significant parts of Sheet 71 (Glenelg, published in 1909).
One of the preeminent geologists of the Geological Survey of Scotland from 1884 until his tragic death in 1916 when struck by a train in a narrow railway cutting south of Bo’ness whilst surveying. He contributed significantly to the mapping and interpretation of the complex rocks of the Moine Thrust Zone/Belt in NW Scotland, including the southernmost section in SE Skye on the Scottish Geological Survey Sheet 71 (Glenelg, published in 1909). Recognized by the Edinburgh Geological Society by their annual award of the Clough Medal.
One of the preeminent geologists of the Geological Survey of Scotland from 1862 until his retirement in 1905. He contributed significantly to the mapping and interpretation of the complex rocks of the Moine Thrust Zone/Belt in NW Scotland, including the southernmost section in SE Skye on the Scottish Geological Survey Sheet 71 (Glenelg, published in 1909).
