Jethro Teall

from Wikipedia, the free encyclopedia

Sir Jethro Justinian Harris Teall (born January 5, 1849 in Northleach , † July 2, 1924 in London ) was a British geologist and petrologist who was considered one of the most respected British geologists of his time.

Teall studied at St. John's College at Cambridge University and was a fellow of his college from 1875 to 1879. Teall was financially independent. He is known as the pioneer of petrography in Great Britain and was made a Fellow of the Royal Society specifically for his monograph on it. In the 1880s he worked with Charles Lapworth , whose work from the geological survey of Scotland he presented when he fell ill with a mental illness. In 1888, Archibald Geikie brought him to the British Geological Survey as an expert on metamorphic rocks, for which he also mapped large areas in north-west Scotland and whose director he was from 1901 as Geikie's successor.

In 1889 he received the Bigsby Medal and in 1905 the Wollaston Medal . In 1874 he received the Sedgwick Prize for studies on the British Cretaceous green sandstone (Lower Greensand). In 1890 he became a Fellow of the Royal Society and in 1921 an Honorary Fellow of the Royal Society of Edinburgh . He has three honorary doctorates ( Dublin , Oxford , St. Andrews ). In 1916 he was knighted as a Knight Bachelor for his work at the Geological Survey, which he reformed organizationally . He was President of the Geological Society of London .

The mineral Teallite from the Kylindrite group and the Teall Nunatak and Cape Teall are named after him. In 1907 he and colleagues identified the Moine Thrust in Scotland as a thrust belt, the first such identification at all.
