Christopher Eastoe


I’m gay and I’m a geologist, geochemist, and retired university professor. //

I studied geology at the University of Tasmania, completing a PhD in Economic Geology under the supervision of Dr. Mike Solomon in 1979. My doctoral research focused on fluid inclusions and stable isotopes in the porphyry copper deposit on the island of Bougainville. In 1982, I took up an assistant professorship at the University of Arizona. I spent the rest of my professional career at the U of A. My research interests gradually evolved toward applications of isotope geochemistry in the hydrologic cycle, atmospheric composition, paleoclimate, and sedimentary basins. Retired since 2015, I continue to write scientific articles, collaborate with colleagues in the USA, Mexico, India, Kuwait and China, and advise graduate students.
