Christopher Hawkesworth

Christopher John Hawkesworth, called Chris Hawkesworth ( born December 18, 1947 in Khartoum ), is a British geochemist ( Isotope Geochemistry ) and geologist. He is a professor at the University of St. Andrews.

Hawkesworth grew up in Ireland. He studied at Trinity College, Dublin (Bachelor 1970) and in 1974 at the University of Oxford doctorate with a thesis that ( southeast corner of the Tauern window) was created as part of the development of a thermal model of the orogen in the Eastern Alps. From 1975 he conducted research at the University of Leeds and from 1978 he was a lecturer at the Open University, where in 1980 he built a geochemical isotope laboratory and in 1988 professor of geochemistry was. From 2000 he was a professor at the University of Bristol and its director of the Science Faculty (Science Faculty ). Since 2009 he has been Deputy Principal and Vice - Principal of Research at the University of St Andrews.

He was Founding Fellow in 1995 from the University of Auckland in 1986 and a visiting scholar at Stanford University.

He examined with geochemical methods the processes in magmas of volcanoes and the mass balance in subduction zones and is concerned with the origin and evolution of continental crust. He examined the conditions violent meteorite bombardment of the crust and large melt pools, which resulted in the Earth's past to break the super continents. He is also studying the interactions of biological and inorganic geochemical processes in the early Earth and tested generally age determinations with radioactive isotopes, for example in the context of enlargement of the temporal range of radiocarbon dating by examination of stalactites in the Bahamas. He also examined climate change over the past 150,000 years based on the isotope content of pollen in cave sediments.

After Hawkesworth and colleagues created (due to the then increased Erdmanteltemperatur ) the majority of the Earth's crust only in the period between about 4.5 and 3 billion years from oceanic crust.

In 2012 he received the Wollaston medal. In 2008 he was awarded the Wolfson Merit Award from the Royal Society. He is a Fellow of the Royal Society (2002) and the Royal Society of Edinburgh (2012 ) and the American Geophysical Union, the Daly Lecture he gave in 2002. In 2002 he received the Schlumberger Medal from the Mineralogical Society. He received the Major John Coke Medal of the Geological Society of London and an honorary doctorate from the University of Copenhagen. He is a Fellow of the Geochemistry Society and the European Association for Geochemistry. He is the author of over 280 publications and supervised 57 PhD students ( 2009).

He is co-editor of the journals Geology and Earth and Planetary Science Letters.

Hawkesworth is married and has one daughter.
