UMâs Rosenstiel School of Marine & Atmospheric Science Welcomes:
Dr. Mark Thiemens
UM Alumnus, Goldschmidt Medalist, Member of the National Academy, Dean
of the Division of Physical Sciences at University of California â San Diego, and All-Around Good Guy

"Mass Independent Isotope Effects and Application to
Climate Change and the Origin and Evolution
of Oxygen of Earth & Mars"
Thusday, April 8, 2010
3:00 PM
Rosenstiel School Auditorium


Dr. Thiemens' work on atmospheric ozone, and his subsequent studies of isotope fractionations
in other elements pertaining to atmospheric chemistry and rock-gas interactions, have shown
that mass independent fractionations can, and do, take place in nature. This realization has
opened whole new avenues of geochemical research. He has even had a minor planet orbiting
the inner part of the main asteroid belt designated (7004) Markthiemens in honor of his
groundbreaking work with meteorites.
