Eric J. Essene

from Wikipedia, the free encyclopedia

Eric J. Essene (born April 26, 1939 in Berkeley , † May 20, 2010 in Ann Arbor ) was an American geologist and petrographer.

Essene graduated from the Massachusetts Institute of Technology with a bachelor's degree in 1961 and received a PhD in geology from the University of California, Berkeley in 1967 . He was a post-doctoral student at Cambridge University and at the Australian National University from 1968 to 1970 . In 1970 he became an assistant professor and later professor at the University of Michigan .

He dealt with (chemical) thermodynamics of the earth's crust and mantle and is known for his contributions to the petrography of metamorphic rocks, in particular for indications of their formation conditions in the earth's crust (temperature, pressure) and the speed with which they were brought back to the earth's surface . In particular, he researched in the 1 billion year old crystalline of the Grenville Mountain Belt (which stretches from the Adirondack Mountains to the northeast of the Labrador Peninsula ). Essene also helped characterize various minerals and was co-author of the first descriptions of Coskrenite (Ce) , Zugshunstite (Ce) and Levinsonite-Y .

In 2010 he received the Penrose Medal and in 1991 the Bowen Medal of the American Geophysical Union. In 1993 he received the first Sokal Award from the University of Michigan for his teaching. In 1981 he became a Fellow of the Mineralogical Society of America and in 1991 of the American Geophysical Union . In 1987 Donald R. Peacor and Michael A. Cosca named a new pyrometamorphic pyroxene mineral from Durham Ranch in Wyoming , United States , the first stage of which he discovered, in his honor as Esseneit .
