Ralph J. Roberts (geologist)

from Wikipedia, the free encyclopedia

Ralph Jackson Roberts (born January 31, 1911 in Rosalia (Washington) , † August 10, 2007 ) was an American geologist . He was an expert on the geology of Nevada and, as a result of his research, large gold fields were discovered there.

Goldstrike Mine, Carlin, Nevada

Roberts studied geology at the University of Washington in Seattle with a bachelor's degree in 1935 and a master's degree in 1937 and received his doctorate in 1948 from Yale University . In his dissertation, which also included the geological mapping around Antler Peak in the Battle Mountains of Nevada, he introduced the Antler Orogen , which took place in the Carboniferous ( Mississippium , early Pennsylvania ) as the earliest local orogeny phase . From 1939 he was with the US Geological Survey , mostly in Nevada and Utah, where he explored the mountain ranges and their formation and the mineral deposits. During the Second World War, he worked as a geologist in Central America from 1942 to 1945. A work from 1960 ultimately led to the discovery of some of the richest gold deposits in the United States ( Carlin , Cortez-Battle Mountains) in the 1980s. Roberts, who left the Geological Survey in 1981, helped develop it as a consultant to mining companies.

From 1972 to 1978 he was a consultant on mineral exploration in Saudi Arabia.

In 1991 he was named Mining Man of the Year from the American Institute of Mining Engineering. In 1983 he received the Distinguished Service Award from the US Department of the Interior and he received the Distinguished Service to the Minerals Industry Award from the Northwest Mining Association.

An economic geology research center at the University of Nevada at Reno is named after him.
