Kent Condie

from Wikipedia, the free encyclopedia

Kent Carl Condie (born November 28, 1936 in Salt Lake City ) is an American geologist and geochemist . He is Professor Emeritus of Geochemistry at the New Mexico Institute of Mining and Technology .

Condie became interested in geology when he led white water rafting trips on the Colorado River in college . He studied at the University of Utah with a bachelor's degree in 1959 and a master's degree in 1960 and received his doctorate in geochemistry with Albert Engel at the Scripps Institute of Oceanography in San Diego in 1965 ( Petrology and geochemistry of the late Precambrian rocks of the northeastern Great Basin ). He turned down the opportunity to do a doctorate with Harold Urey on the origin of the moon. In 1964 he became an assistant professor and later an associate professor of geochemistry and petrology at Washington University . He has been Associate Professor since 1970 and Professor of Geochemistry at the New Mexico Institute of Mining and Technology since 1977.

He deals with the geochemistry of trace elements and the development and origin of the continents. He is known for big data analysis of geochemical data to reconstruct the formation of the crust in the first two to three billion years of the earth's history. For example, he examined greenstone belts of the Archean in order to deduce the beginning of plate tectonics from the conditions in which they were formed, and he examined granites at the boundary between the Archean and Proterozoic . After investigating some unusual greenstone deposits in Canada in the 1990s, which came from oceanic plateau basalts from mantle plumes , he deals with the role of mantle plumes in the history of the earth, about which he published a monograph in 2001. As a professor, he also led summer field excursions (rafting) on ​​the rivers in the southwest of the USA for many years. He has been on field excursions around the world (Africa, Western Australia, Northern Europe, China, Siberia), but dealt particularly intensively with the geology of Colorado and New Mexico and South Africa (since 1973). Condie published several books on plate tectonics and their evolution, first in 1976 Plate tectonics and crustal evolution , which had four editions by 1997.

In 2018 he received the Penrose Medal . In 2007 he received an honorary doctorate from the University of Pretoria. In 1987 he received a Distinguished Research Award from New Mexico Tech.
