Helge Backlund

from Wikipedia, the free encyclopedia

Helge Götrik Backlund (born September 13, 1878 in Dorpat , † January 29, 1958 in Uppsala ) was a Swedish geologist and paleontologist. He dealt mainly with petrography and tectonics of Scandinavia, northern Russia and the arctic regions of Siberia.

Life

Helge Backlund was the son of the astronomer Oskar Backlund (1846–1916) in Dorpat, later director of the Pulkowo Observatory . His sister was the Russian-Swedish artist Elsa Backlund-Celsing (1880–1974).

Backlund studied geology in Saint Petersburg (graduating in 1902) and in Vienna , where he received his doctorate in 1908. From 1899 to 1901 he took part in the Russian-Swedish expedition to Svalbard to measure degrees , during which he succeeded on August 4, 1900, the first ascent of the Newton top . In 1904 an expedition followed to northern Siberia (to the Yenisei and the lower reaches of the Chatanga ), in 1909 one to the northern Urals and the Arctic Sea (to the lower reaches of the Ob ). In 1909 he became curator at the Geological Museum of the Russian Academy of Sciences in Saint Petersburg, and from 1911 he became chief curator. In 1911 he was looking for oil in Turkestan . From 1912 to 1913 he was a state geologist in Argentina. From 1913 to 1914 he traveled to North and South America, in 1915 to Altai and northern Mongolia, in 1916 to the Urals and again in 1917 to northern Mongolia. In 1918 he became a professor at the Åbo Academy .

Backlund advocated the hypothesis of granite formation from sedimentary rocks under the influence of gas emanation . He reworked the stratigraphy of archaic and Proterozoic rocks of the Baltic shield and determined common sedimentation cycles in the Gothokarelids. In 1909 he researched the geology of the Arctic Urals and 1911 to 1913 tin deposits in Argentina and Bolivia.

In 1943 the Geological Association awarded him the Gustav Steinmann Medal . He was a member of the Swedish Academy of Sciences , the Göttingen Academy of Sciences . and the Royal Society of Edinburgh .
