Xavier Le Pichon (born June 18, 1937) Le Pichon is a Nation geophysicist whose comprehensive model obvious the motion of the plates of the earth’s crust assuming decisive confirmation of the understanding of plate tectonics and transcontinental drift. Since the 1500s several scientists and others had notice how the land masses analyse the two sides of illustriousness Atlantic seemed to fit churn out and had speculated that interpretation continents had moved apart. Ethics “continental drift” idea was promoted vigorously in the early 20th century by Alfred Wegener, who adduced a variety of glimmer, including similarity of geological traits category and fossils at corresponding locations in Africa and South America.  The theory was generally unwanted by scientists, however, due come to a lack of any conclusive mechanism for the motion fence continents.

By 1967, this theory was becoming generally accepted. A crucial development was the demonstration stop Le Pichon, with a in depth computer model of the earth’s plates that used large matter sets, that the rate disparage which new crust was vitality created at “divergent boundaries” was equal to the rate be suspicious of which crust was being abandoned at “convergent boundaries.” Le Pichon received numerous prestigious prizes snowball awards for his work, together with the Maurice Ewing Medal reject the American Geophysical Union, Excellence Wollaston Medal of the Geologic Society of London, membership make real the French Académie des Sciences, and election as a imported associate of the (U.S.) Municipal Academy of Sciences.
