Francis John Turner was a New Zealand geologist
Geologist
A geologist is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes and history that has shaped it. Geologists usually engage in studying geology. Geologists, studying more of an applied science than a theoretical one, must approach Geology using...

At Otago he became interested in metamorphism
Metamorphism
Metamorphism is the solid-state recrystallization of pre-existing rocks due to changes in physical and chemical conditions, primarily heat, pressure, and the introduction of chemically active fluids. Mineralogical, chemical and crystallographic changes can occur during this process...

 and was a great influence on a generation of geologists.

In 1946 he accepted a position at the University of California in Berkeley. At Berkeley he gained insight into experimental studies of petrology and geochemistry. He later collaborated with John Verhoogen on the classic work Igneous and Metamorphic Petrology published in 1960. He authored eighty technical papers and six textbooks on metamorphic, igneous, and structural petrology. He retired from Berkeley in 1971.
