T. Mark Harrison
T. Mark Harrison is an isotope geochemist based in California. He is Distinguished Professor of Geochemistry in the Department of Earth, Planetary and Space Sciences, University of California – Los Angeles. Education A native of Vancouver, Canada, Harrison received his B.Sc. (Hons.) from the University of British Columbia, in 1977. His Ph.D. research from 1978 to 1980 developing 40Ar/39Ar thermochronology was conducted under the supervision of Prof. Ian McDougall at the Australian National University. Academic life Following a postdoctoral fellowship at the Carnegie Institution of Washington, Harrison spent 8 years on the faculty of the Department of Geological Sciences at the State University of New York at Albany rising from Assistant to Full Professor. In 1989, he moved to UCLA where he served as Chair of the Department of Earth and Space Sciences from 1997 to 2000 becoming a Distinguished Professor in 2003. He took leave from UCLA to take up an appointment as Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geochemistry
Geochemistry is the science that uses the tools and principles of chemistry to explain the mechanisms behind major geological systems such as the Earth's crust and its oceans. The realm of geochemistry extends beyond the Earth, encompassing the entire Solar System, and has made important contributions to the understanding of a number of processes including mantle convection, the formation of planets and the origins of granite and basalt. It is an integrated field of chemistry and geology. History The term ''geochemistry'' was first used by the Swiss-German chemist Christian Friedrich Schönbein in 1838: "a comparative geochemistry ought to be launched, before geognosy can become geology, and before the mystery of the genesis of our planets and their inorganic matter may be revealed." However, for the rest of the century the more common term was "chemical geology", and there was little contact between geologists and chemists. Geochemistry emerged as a separate discipline after ...

University Of California – Los Angeles
The University of California, Los Angeles (UCLA) is a public land-grant research university in Los Angeles, California. UCLA's academic roots were established in 1881 as a teachers college then known as the southern branch of the California State Normal School (now San José State University). This school was absorbed with the official founding of UCLA as the Southern Branch of the University of California in 1919, making it the second-oldest of the 10-campus University of California system (after UC Berkeley). UCLA offers 337 undergraduate and graduate degree programs in a wide range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students. UCLA received 174,914 undergraduate applications for Fall 2022, including transfers, making the school the most applied-to university in the United States. The university is organized into the College of Letters and Science and 12 professional schools. Six of the schools offer undergrad ...
