Adolf Helke

from Wikipedia, the free encyclopedia

Gottfried Adolf Helke (* 14. September 1902 in high Weitz's in Döbeln ( Saxony ); † 23. November 2006 in Mainz ) was a German geologist , mineralogist and deposit watchers .

Life

After attending elementary and secondary school (up to Quarta ) in Leisnig , Adolf Helke went to the Princely School in Grimma (until Easter 1923 ). Then he studied at the Freiberg Mining Academy , the mountain specialist ( Mine Surveying ). In the fall of 1925 he passed the preliminary examination and in May 1927 the main examination for the subject of mark separator . After that he worked until August 31, 1927 as a research assistant at the Institute for Geodesy and Landscaping of the Freiberg Mining Academy.

From September 1, 1927 to March 31, 1929 , Helke worked as a surveyor and geometer on a manganese ore mine near Fethiye in Anatolia ( Turkey ). He then began a second degree at the Bergakademie in Freiberg and passed the main examination for the subject of mining engineering at Easter 1930 . For his diploma thesis, he returned to Anatolia for several weeks in autumn (August / September) 1929 to study the mining geological conditions of the Au-Ag-Pb-Zn deposit of Bulgar Maden in the Cilician Taurus . In 1930 he made a short stay at the Bulgarian state coal mines in Pernik near Sofia (Bulgaria).

From May 1930 to April 1933 he worked as a mining engineer at the Rudaer 12 Apostle Union in Brad ( Transylvania, Romania ). During this time he began his dissertation with the title Contributions to the knowledge of the gold ore veins on the Ungarberge and on the Fericel near Stanija in the Transylvanian Ore Mountains, Romania , which he completed in July 1931 . In May 1932 he obtained a doctorate for this at the Bergakademie Freiberg.

From May 1933 to February 1937 Adorf Helke worked as a scientific assistant at the Geological Institute of the Freiberg Mining Academy with Friedrich Schumacher . During this time he went on two-monthly study trips through the mining districts of the Carpathian Mountains (including the gold tellurium deposits of Nagyág (now Sacarimb) in Transylvania ) during the academic summer vacation . In February 1937 , he completed his habilitation on The Young Volcanic Gold-Silver Ore Deposits of the Carpathian Arc with special consideration of the genesis and paragenesis of the solid gold . From March 1937 to October 1938 he worked as a mining engineer at the Mineral Deposit Research Institute ( Maden Tetkik ve Arama Enstitüsü ) in Turkey in Ankara. In 1938 he went on a study trip from Ankara to Bor and Trepča (Yugoslavia), Bleiberg, Eisenerz and Radenthein (Austria), and Raibl (Italy).

From November 1938 to November 1939 he was a fellow at Johns Hopkins University in Baltimore , Maryland. He then traveled to the United States of America for four months until March 1940 to visit all the major geologically interesting mines (ores, non-ores). The return journey to Germany took place via Japan and Siberia.

From April 1940 to 1945 Adorf Helke worked again as a scientific assistant at the Geological Institute of the Bergakademie Freiberg under Professor Friedrich Schumacher . 1942 he stayed on studies of Paleozoic in Estonia and in January 1943 for incorporation in the structure of customer with Professor Bruno Sander at the Mineralogical-Petrographic Institute of the University of Innsbruck . During his time as an assistant at the Bergakademie Freiberg, he led the ore microscopy exercise for geologists and gave a lecture on selected chapters from the theory of deposits .

His scientific career was suddenly interrupted by military service and imprisonment. He continued his work in Turkey after the war: from 1948 he headed an antimony mine, then became a lecturer in geosciences at a college for mining engineers and chief geologist at the state mines.

In 1956 he accepted a call to the Johannes Gutenberg University in Mainz , where he took over the chair for deposit science . Six years later he completed his habilitation again, this time on the occurrence and formation of chromium deposits .

Even after his retirement in 1967 , he still held lectures and training sessions on ore deposit science. In 1987 he was awarded the Hans Schneiderhöhn Prize for special merits from the Rhenish Natural Research Society (RNG) and the Mainz Natural History Museum .

Adolf Helke died on November 23, 2006 at the old age of 104 in Mainz.
